Greg Cassoli: It's hard to ignore Isaiah Thomas's playoff performance, particularly his 53-point game, but I'm going to do it because I'm a sucker for Paul Pierce. The Truth's basketball adolescence mirrored my actual developmental years, a time when I was falling in love with basketball. I embraced his arrogance and celebrated his skill, which was immense. I was lucky enough to be at his final game at the Garden, and I was proud of the way the fan base sent him off. His three in the final minutes will be my enduring memory of this season.
Keith Smith: The Christmas Day win over the Knicks. For one, the Celtics were back to playing on Christmas. That is an honor reserved for the best/most interesting teams in the league. Second, the team was 17-13 entering that game—good, but not great or anything. That victory kicked off a run that saw Boston go 36-16 the rest of the way and established them as one of the league's best teams.
Alex Kungu: Jaylen Brown’s first game against the Cavaliers was one of the memorable moments of the season. Up to that point of the season, Brown was starting to win the Celtics fans over, but it was this game where his potential was truly shown to the Celtics fanbase.
Jared Weiss: Avery Bradley’s game-winning three in Game 3 of the Conference Finals in Cleveland. This was Stevens’s masterclass performance, running three ATOs in the final minute to perfect execution. They had just lost Isaiah Thomas for the season and came off their worst loss ever. They could have been completely humiliated and walked out of the playoffs with their tail between their legs. Then Stevens said after Game 2 that they were going to leave that all behind and go to Cleveland and get a win. Their gameplan was phenomenal, and their adjustment in the second half to go to Jonas Jerebko triggered a 21-point comeback. The finish was thrilling, with the ball bouncing around the rim like the Celtics had put it all on black. In the end, it came up green. What a night.
