In a recent development, the NBA has officially sided with Boston Celtics head coach Joe Mazzulla regarding a controversial play involving Pascal Siakam. The league's Last Two Minutes Report, released on Tuesday, stated that Siakam's screen was indeed illegal during the game against the Boston Celtics.

The incident occurred in the closing moments of the game, where Siakam set a pick that appeared to be within the rules. However, upon review, the NBA determined that the screen violated the league's regulations, which led to Mazzulla's assertion that the play should not have been allowed.

Coach Mazzulla had argued that Siakam's screen was illegal because it involved a moving pick that impeded Celtics players unfairly. His objections gained further support when the NBA confirmed the ruling in its official report, which analyzes critical plays in the final minutes of games to ensure fair officiating.

The report specifically highlighted that Siakam's screen was set illegally because he was moving at the time, which is against the rules governing legal screens. This clarification is significant because it impacts the outcome of the game, which was decided by a game-winning shot by the Celtics.

The league's decision underscores the importance of adhering to the rules of fair play and the league's commitment to officiating integrity. It also validates Mazzulla's stance, providing clarity on the legality of the play and reinforcing the league's role in maintaining competitive fairness.

Fans and analysts have debated the call extensively, but the NBA's official stance now confirms that the play was indeed illegal. This ruling may influence how future screens are set and officiated, emphasizing the need for players to stay stationary during picks to avoid infractions.

Overall, the NBA's support for Mazzulla and the declaration of Siakam's screen as illegal highlight the league's ongoing efforts to ensure that games are played within the rules and that officiating decisions are transparent and consistent.
