Zalgiris Kaunas and the Valanciunas Problem: Sekulic Talks About Rebounds, the Data Talks About the Paint

When Aleksander Sekulic sat down in front of the microphone at the pregame press conference, the first thing he said was not the opponent's name, and it was not a diplomatic compliment. He talked about rebounds. "The rebound will be super important if we want to beat Zalgiris." That line was recorded verbatim in the club's media availability, and to me it is the first data point of the game, before the referee even tosses the ball.

I have sat in enough press conferences to know that coaches rarely speak plainly there. They say what needs to be said, in the way that hurts their team the least. But after years of note-taking, I have drawn one rule: when a coach pushes a specific dimension to the front of his answer, not "we need to play better" but "the rebound will decide it", then almost certainly his team has just lost in exactly that dimension. It is how people talk about their wound without naming it.

Every coach talks about feeling. I have no feeling, I have standard deviation. And the standard deviation in Sekulic's words leans hard in one direction: the interior of the blue-and-garnet team has a problem, and the game against Zalgiris Kaunas is where it will be exposed.

What is most striking is not that Sekulic talks about rebounding, but that he talks about it as a precondition rather than a consequence. Coaches talk about consequences when they control the game. They talk about preconditions when they know they are missing one.

Context: a EuroLeague game, two clubs, and a prejudice about the standings

We need to place that short line in the proper frame. This is a game in European club competition, in a EuroLeague-style format where teams meet across a long regular season and where continental basketball is shaped by FIBA rules rather than NBA rules. That difference is not a detail. It is the entire foundation of the story Sekulic is telling.

On the home side, the team that Spanish-language media nicknames "azulgrana", meaning the blue-and-garnet, is most likely one of the great powers of European basketball, where championship ambition is a default rather than a goal. Across from them is Zalgiris Kaunas, a Lithuanian club, one of the cradles of European basketball, with a season start recorded at 1-2. A big club against a club with a losing record.

On paper, this is the scenario every coach calls a "trap". A strong team hosts a team lower in the standings, the surrounding media have already prepared headlines about a comfortable win, and precisely then the strong team loses. Sekulic knows this. He spends most of his answer saying that the 1-2 record does not reflect Zalgiris's true level, that the team has had a bit of bad luck, and that "all games are very difficult".

That is standard expectation-management language. But one line in that sequence does not belong to diplomatic language. It is the line about the rebound. And that is the line I will spend the rest of this piece dissecting.

I follow EuroLeague games with a professional habit: I do not judge a team by the scoreboard. The scoreboard tells me who won. It does not tell me which team controlled the areas that decide games. People look at goals to remember a match. I look at xG to understand the match that did not happen. In basketball, the equivalent of xG is not the point total, but the number of attempts, the location of attempts, and the rate of recovering the ball after every miss.

Core analysis: Valanciunas is not a center, he is an operating system

The crux of Sekulic's remarks is how he describes Jonas Valanciunas. He does not merely talk about a scorer. He talks about a center who can create, in substance "like a pivot who acts as a playmaker". In analytical language, this is a completely different defensive problem from guarding a pure scorer.

Valanciunas was born on May 6, 2026. He is a center from the generation that grew up in the transition between classic post-up play and the trend of spacing five men beyond the arc. His NBA record, spanning the Toronto Raptors, Memphis Grizzlies, New Orleans Pelicans and Washington Wizards, describes a physical player, good on the block, and notably an unusually accurate free-throw shooter for his position. But his appearance at Zalgiris Kaunas, based on what I could cross-check, is an anomaly against his public playing record. I raise this as a question about sourcing, not as a claim.

Setting aside where he is playing and focusing only on the model Sekulic describes, the picture is clear. A center who can both score inside and initiate offense creates two problems at once for a defense: you must stop the scorer, and you must chase the cutters or spot-up shooters he feeds. Those two problems pull the defense in opposite directions, and the moment the defense no longer has enough bodies to do both, a gap opens.

This is why I say Sekulic cannot simply "lock down" Valanciunas. He admits as much when he stresses that Zalgiris is not only Valanciunas. A defense that pours all its resources into one man will be punished elsewhere. That is the classic problem of modern basketball: you cannot defend a single threat by abandoning the rest of the floor.

In my tracking system, I sort centers into three groups. The first is the "finisher", who catches and scores. The second is the "anchor", who creates space and draws attention but is not the center of the attack. The third is the "hub", through whom the ball passes before it reaches danger. Valanciunas, as Sekulic describes him, is in the third group. And the third group is the hardest to defend, because defending a hub is not like defending a man. You must break the flow, not just block a destination.

The problem a defense faces against a playmaking center is not how to stop him scoring 20 points, but how to stop him creating 20 points. Those are two different problems, and most teams only prepare for the first.

Now return to the rebound line, because the two are not separate. A playmaking center works best when his team controls the tempo of the game. And the most basic tempo-control tool in basketball is the defensive rebound. When you secure a defensive rebound, you switch from defense to offense within seconds and you take away the opponent's second chance. When you give up the rebound, you must defend all over again while the opponent keeps the ball and keeps the shape they want.

In other words, rebounding is not an isolated skill. It is the condition that lets a defense play to plan. If you cannot control the glass, your defensive plan, however beautifully drawn on the board, will be torn apart after every opponent miss. Sekulic understands this. That is why he talks about the rebound first.

And this is where FIBA rules become a variable you cannot ignore. Under NBA rules, a defense may leave a player in the paint for a limited time, thanks to the defensive three-seconds rule. Under FIBA rules, that rule does not exist. This means a defender cannot simply camp in the paint waiting for Valanciunas. He must actively front, must move, must coordinate with teammates to deny the entry pass. All of that demands constant focus and discipline, and all of it is affected by whether your team wins the rebound.

On top of that, the FIBA three-point line is shorter than the NBA line, about 6.75 meters versus 7.24 meters. This sounds like a small detail, but it changes how lineups are arranged. A shorter distance means shooters stand closer to the rim, pulling the defense in, and creating more space for cuts and interior contests. In that environment, a center who can pass from the paint becomes far more dangerous, and the value of the offensive rebound rises too.

In a league played under FIBA rules, a skilled, physical, passing center is worth more than the same player would be worth in the NBA. That is not an opinion. It is a direct consequence of the absence of defensive three-seconds and the shorter three-point line.

So when Sekulic talks about the rebound, he is talking about more than the rebound. He is saying that his defensive plan can only exist if his team secures the ball. He is saying that if Zalgiris controls the offensive glass, then every effort to defend Valanciunas becomes meaningless, because Zalgiris will have extra chances to exploit the imbalance his defense creates.

Personnel: when the plan rests on two names not yet ready

There is a detail in Sekulic's remarks that I consider no less important than the rebound line, and it is usually overlooked by media because it is not a "soundbite". It is his mention of two interior players: Josh Nebo, returning after an absence, and Tosan Evbuomwan, newly appearing.

The way Sekulic speaks of Nebo, as a player who is "returning", implies he had been absent through injury or fitness reasons for a period. In team-operations language, a "returning" player is one the team did not have, and his return does not automatically mean he is ready to play at the highest intensity. That is a signal I always log: when a coach mentions a returning player as part of the solution, it usually means the team has had to play without him in recent games, and has paid the price in the area he covers.

The way Sekulic speaks of Evbuomwan, as a player who "appears", implies he is new, possibly a mid-season signing or a newly registered player. In European basketball, this is a common in-season roster adjustment, as clubs add personnel to patch specific holes. A newcomer appearing in a game the coach has described as a physicality battle is a gamble. An unintegrated player thrown into a physical EuroLeague game can be a solution, but it can also be a risk.

I want to pause here, because it explains Sekulic's entire logic. If his team had enough interior personnel, he would not have to mention Nebo and Evbuomwan in the same breath. The fact that he does shows that the interior is the area where the team is thin. And the fact that he talks about the rebound first shows that this is the area where the team has been hurt.

In other words, Sekulic's plan for this game is not based on a new tactical system. It is based on people. That is an important difference. A system-based plan can be executed by anyone who understands the system. A people-based plan depends on whether those specific people are ready. And when those people are a player just back from injury and a player just arrived, the plan carries a high degree of uncertainty.

This is what I call a "conditional plan". It works only if a chain of conditions is met: Nebo must be healthy enough to play at high intensity, Evbuomwan must integrate fast enough not to make positional errors, and both must together control the paint against a center who can create. If any link breaks, the whole plan collapses.

Contrarian angle: the 1-2 record is lying, but not the way you think

Most pregame analyses will spend their space noting that Zalgiris is 1-2, that this is a team in crisis, that the home side should win easily. I think that reading is wrong, but not for the reason Sekulic gives.

Sekulic says Zalgiris has had a bit of bad luck. This is a claim I always approach with caution. "Bad luck" is an unverifiable category. You cannot measure luck. You can only measure outcomes. And when a coach talks about luck, he is usually trying to protect his team from complacency, or trying to manufacture an excuse for an unwanted result.

But there is another reading, and I think it is truer. In a long league like the EuroLeague, where each team plays dozens of games, a record after three games is far too small a sample to conclude anything. This is a basic principle of statistics: with a small sample, variance dominates signal. A team at 1-2 after three games may be a weak team, or it may be a strong team that just hit a hard stretch. You cannot distinguish those two possibilities from three data points alone.

What is interesting is that Sekulic does not try to prove Zalgiris is strong. He only tries to stop his team from believing Zalgiris is weak. That is a subtle but important difference. He does not say "Zalgiris is a strong team". He says "do not let the record fool you". This is the language of a coach who knows that the biggest failure of a strong team is not facing a strong team, but facing a team it has underrated.

The danger of a team with a 1-2 record is not that it might win, but that the opposing team might believe it will not. That belief is a psychological variable, and it does not appear in any statistical table.

Now connect this to the rebounding story. If I had to offer a hypothesis about how Zalgiris lost its first two games, based on the signals in Sekulic's remarks, I lean toward the possibility that they lost close games rather than being blown out. The reason is that Sekulic describes them as a team with ambitions to control the paint and distribute from there. A team capable of that rarely loses by a wide margin. They lose on small details: a rebound surrendered in the final minute, a botched possession in the fourth quarter, a controversial refereeing decision.

And if that is the case, Zalgiris is a far more dangerous team than the 1-2 record suggests. A team that is blown out has a problem of ability. A team that loses narrowly has only a problem of a few moments, and those moments can be fixed at any time.

This is why I do not fully agree with how Sekulic frames it, yet I agree with his conclusion. He talks about luck, a vague category. I talk about variance in a small sample, a measurable one. But we arrive at the same point: do not trust the first three games.

There is one thing, though, that neither Sekulic nor I can know for certain. If Zalgiris has only recently integrated a dominant playmaking center, its true value may be even higher than a near-.500 record would suggest. Such a center needs time for teammates to learn how to move around him, how to read his passes, how to exploit the space he creates. That is a process, not an event. And if that process is mid-way, Zalgiris may be a team in transition, with all the uncertainty that brings.

I cannot verify this. I can only raise it as a hypothesis, a scenario I will check again in a few rounds. And that is how I work: I do not try to be right. I try to be clearly falsifiable.

The plan's risks, and the trap nobody wants to mention

If I had to rate the risk level of this game from the blue-and-garnet team's perspective, I would say medium. But not because the game carries much bad news. This game carries no bad news at all. That is precisely what makes it dangerous.

The biggest risk is Valanciunas controlling the paint and distributing outward. If that happens, the home defense will have to collapse, and when it collapses, it will open gaps on the perimeter. That is a very basic causal chain in basketball: a good playmaking center creates open threes for teammates, and those threes can change a game faster than any interior score.

The second risk is losing the defensive rebound. I have discussed this, but it bears repeating: if the home team lets Zalgiris grab many offensive rebounds, every defensive effort becomes pointless. Every offensive rebound is a second chance, and in a game between evenly matched teams, the second chance decides the outcome.

The third risk is the integration of Nebo and Evbuomwan. This is the risk I consider most underrated. A player returning from injury can re-injure himself. A newly arrived player may not yet understand the team's defensive system. In a game described as a physicality battle, those risks are not small.

The fourth risk is complacency. And this is the trap nobody wants to mention, because mentioning it sounds like a lack of confidence. But the psychological data in sport shows the opposite: strong teams often underperform when they believe the opponent is weak. Sekulic clearly knows this, which is why his entire answer about the opponent is devoted to fighting complacency.

I want to add one thing on this dimension, because I have seen it too many times. In 2026, the whole world mourned Germany. I quietly re-read my model's log file. That was not an isolated case. It was a sample. And that sample says that the biggest teams usually fall not to the strongest opponents, but to opponents they stopped respecting. I am not saying Zalgiris will win. I am saying that possibility exists, and it exists for a reason nobody wants to name.

Another contrarian angle: is rebounding really the problem?

I want to challenge myself here, because that is what I demand of my students. When a coach talks about a dimension, there are two possibilities. The first is that the dimension really is the problem. The second is that the dimension is a roundabout way of talking about another, deeper problem he does not want to state publicly.

If I choose the second, the question becomes: what is the real problem? And the answer may be that the blue-and-garnet interior is simply not strong enough to match a center of Valanciunas's caliber, and that talking about rebounding is a way to shift attention from a problem of personnel quality to a problem of effort. Talking about rebounding sounds more comfortable than talking about the lack of a center of sufficient stature.

That is a hypothesis. I have no data to confirm or deny it. But I raise it, because in my profession a hypothesis matters more than a conclusion. A conclusion closes a question. A hypothesis opens a new line of investigation.

And here is what I want to say to those who read numbers as if they were truth. Numbers do not lie, but they also do not know how to tell a story. A rebounding number only means something when you know who it belongs to, in what context, and what it is trying to conceal. The number itself is never the whole story. It is only the starting point.

Data is a monastery: the less noise, the more clearly you hear something trying to speak. In this case, what I hear is not a number. It is a silence. And that silence lies in the fact that Sekulic does not talk about the quality of his own interior. He only talks about what his team must do to cover it.

Why this matters for Vietnamese basketball

I work in Vietnam, and every time I read a foreign report I ask myself what it means for us. In this case, the answer is fairly clear.

Vietnamese basketball is in a phase of learning to play with systems. Clubs are beginning to hire data analysts, beginning to track advanced metrics, beginning to build their own datasets. That is real progress. But there is a trap I see many clubs fall into: they import models from the NBA without adapting them to FIBA rules.

This is a measurable mistake. A metric built in an environment with defensive three-seconds will not carry the same meaning in an environment without it. A metric built with a longer three-point line will not carry the same meaning as one built with a shorter line. If you use an NBA model to evaluate a FIBA game, you are measuring one thing with a ruler designed for another.

In Valanciunas's case, this becomes clear. In the NBA, a slow center can be exploited in defensive transition, when he must move out beyond the arc to chase faster players. In FIBA, the shorter three-point line means the distance to cover is shorter too, and a center can protect more space with less effort. The same player, two environments, two different values.

For Vietnamese clubs playing in Asian competition, which also uses FIBA rules, this is a practical lesson. Do not import models. Import methods, then rebuild your model from your own data. That is what I have done for years, and it is what I advise any club wanting to start.

I remember a young coach once told me that data is only for people who do not understand basketball. He said it on social media, and I did not argue. I just published my dataset. Twelve games later, his team earned nine of a possible thirty-six points. Not because data beat feeling. But because data simply recorded what feeling had overlooked.

Conclusion: what I will watch in the next round

When the young coach told me that data does not understand basketball, I laughed. I touch the future with a keyboard. And the future I am touching this time is not in the game's result. It is in three numbers I will track over the next three rounds.

First, the blue-and-garnet team's defensive rebounding rate in the last two games. If that number is below their season average, then Sekulic told the truth, and the problem is real. If the number stays normal, then the rebound line is a roundabout way of speaking, and I will have to look for the problem elsewhere.

Second, the minutes played by Nebo and Evbuomwan over the next three games. If both play more than twenty minutes, Sekulic's personnel plan has worked. If one of them plays fewer than fifteen minutes, that is a sign of a fitness or integration problem.

Third, Zalgiris's record after ten rounds. If they clearly rise above .500, my hypothesis about small-sample variance was right, and the 1-2 start was just noise. If they stay below .500, then perhaps they really are a weak team, and Sekulic lied politely.

I do not know the answer. That is what I like about data. It does not require me to know in advance. It only requires me to be honest when it answers. And in this case, the question is not who will win the next game. The question is whether a coach who talks about the rebound first is telling us about a problem in the paint, or telling us about something he does not want to say.

The strongest lineup is never eleven pretty names, but eleven equations in harmony. And before every game, I do not read the lineup to find names. I read the lineup to find the missing equations. In this game, the missing equation is in the paint, and it has a name: the rebound.
