Earlier this week Joe Mazzulla said he couldn’t wait to read the NBA’s Last 2-Minute Report from Monday’s controversial loss to the Indiana Pacers, which confirmed that two incorrect calls had gone against the Celtics on the final possession.

But whether they felt vindicated or not, the Celtics head coach said the most important thing going forward is that they put Monday behind them and avoid getting in a similar position again in the future.

“They have a right to be pissed about that situation, I don’t think that’s wrong, but at the end of the day if we try to act like that’s the main reason we lost then we’re not getting the perspective and the lesson that we need to,” Mazzulla said. “To me we have to focus on the third quarter and we shouldn’t be in that situation.”

In Monday night’s eventual 133-131 loss to the Pacers, the Celtics led 68-59 at halftime before allowing Indiana to score 44 points in the third quarter. The game wound up coming down to the wire, and in the final seconds a Buddy Hield foul on Jaylen Brown was overturned after a Pacers’ challenge, and then on the other end Kristaps Porzingis was called for a foul against Bennedict Mathurin that allowed the Pacers to win the game at the free throw line.

The NBA’s subsequent Last 2-Minute Report concluded that the overturned challenge on the Hield foul was the correct call, but also that Porzingis shouldn’t have been called for a foul. The NBA also said a foul should have also been called on Myles Turner for a moving screen on Derrick White just prior to the Porzingis foul as well.

Mazzulla said he wasn’t aware of the potential moving screen, but even if the officiating errors likely cost the Celtics the game, he feels the best thing for his club is to learn from the adversity rather than dwell on it.

“At the end of the day it’s going to happen again, that’s the nature of the game, and when you look at it from a different perspective it’s another opportunity to get better,” Mazzulla said. “That doesn’t mean you have to be happy about it, but when you stay in it too long you don’t focus on the right stuff.”
