The Celtics looked sloppy on both ends of the floor, shooting poorly, turning it over, and giving up clean looks to the Sixers (mostly Tyrese Maxey). But Kristaps Porzingis started strong and Payton Pritchard shot them back into the game early in the second. They hung around thanks to some aggressive play. Jaylen Brown’s big run at the end of the third quarter gave the Celtics a lead when all the regulars were pulled. The fourth belonged to Payton Pritchard, and his 16 point explosion got the crowd very hyped as the Celtics held on.
