The 129–118 loss to the Los Angeles Lakers was not just another game for the Chicago Bulls. Immediately after the final buzzer, head coach Billy Donovan reacted forcefully, turning frustration into concrete action. According to reports, Donovan submitted an enormous amount of material to the NBA: 170GB of video evidence along with a 60-page analytical report openly challenging the officiating.
Donovan’s decision was far from impulsive. People close to the coaching staff say that already in the third quarter the Bulls coach appeared visibly frustrated by a series of controversial calls. “Billy takes notes even when he’s furious,” revealed an internal source. “We knew he was preparing something big.” That “something” became one of the most detailed complaints ever filed after a single NBA game.
In the document, Donovan argues that without those erroneous decisions the final outcome could have been completely different. He does not focus on isolated incidents, but on a sequence of calls that, in his view, altered the momentum of the game. “We’re not asking for favors,” he reportedly said privately. “We’re asking for consistency and respect for the game.” A statement that sums up the entire complaint.

The report analyzes every disputed possession, supported by slow-motion video, positional tracking, and comparisons with similar situations from other NBA games. According to leaked information, at least ten key decisions had a direct impact on the score. Missed offensive fouls, inconsistent contact calls on both ends of the floor, and ignored violations in crucial moments are all highlighted.
An assistant coach explained that data collection began immediately after the game. “We worked all night,” he said. “Every clip was cataloged, every play compared with the official rulebook.” This was not an emotional protest, but a structured operation designed to force the league to take notice.
Inside the locker room, players reportedly showed full support. One veteran was quoted as saying, “Finally someone is saying what we all see.” While avoiding overly strong public comments, several players share the feeling that certain calls broke the Bulls’ rhythm just as they were trying to mount a comeback.
According to the dossier, the most controversial moment came midway through the fourth quarter, when a referee’s decision immediately led to a Lakers scoring run. “That’s when the game changed,” Donovan states in the report. “Not because of poor execution, but because of external interventions that affected the flow of the game.” Strong words that inevitably fueled debate.
On the other side, the Lakers camp chose silence. There were no official comments on the controversy, only generic statements about referees being part of the game. According to some observers, this was a strategic choice to avoid escalating a league-wide controversy.
The NBA has not issued an official response yet, but internal sources confirm that the materials have been received and will be reviewed. One league executive, speaking anonymously, admitted: “The amount of data submitted is impressive.” This does not guarantee an admission of error, but it makes the case difficult to ignore.

This is not the first time Donovan has spoken out against officiating, but never with documentation of this scale. Those who know him say this move is also about protecting the team. “Billy feels he has to send a message,” explained a former associate. “Not just for this game, but for the future.”
The report reportedly includes statistical comparisons of calls against the Bulls versus other teams in similar situations. According to Donovan, these numbers reveal a worrying pattern. “I’m not talking about conspiracies,” he reportedly clarified. “I’m talking about numbers and images.” A crucial distinction that avoids direct accusations while still raising serious questions.
Chicago fans reacted with anger and support on social media. Hashtags related to the game quickly went viral, with thousands of posts calling for greater transparency. “We don’t want excuses,” wrote one fan. “We want games decided by the players.” The general feeling is that Donovan did what many had been waiting for.
From a basketball standpoint, the loss hurts the standings, but its impact may go further. Some analysts believe this stance could influence how Bulls games are officiated going forward. “When you put everything in black and white, you change the dynamic,” commented a former NBA referee.

It remains to be seen how the league will respond. In the past, similar complaints often ended with formal replies and little practical consequence. However, the scale of this dossier is different. “We’ve never seen 170GB of evidence for a single game,” noted an American journalist. That alone could force a deeper review.
For Billy Donovan, the message is clear. He refuses to let the game be defined only by the final score. “Respect for the game comes first,” he reportedly told his players. Whether the NBA accepts his arguments or not, this episode marks a turning point in the relationship between coaches, referees, and the league.
In the end, the loss to the Lakers may become one of the most discussed cases of the season. Not only for what happened on the court, but for what is now unfolding off it. One thing is certain: Billy Donovan chose not to stay silent, and his actions will continue to spark debate for a long time.
