From the Celtics’ first game on December 23rd through the end of February 2021, the team held their opponents under 100 points a total of four times. In the months of March and April, they’ve done it six times, five of which came after the trade deadline. After splitting a back-to-back against the Phoenix Suns and Brooklyn Nets, the Celtics hold the 3rd best defensive rating over their last 15 games.
The narrative all year has been the Celtics weren’t playing with energy and urgency.
