I was wondering if DeRozan might be half a step slower on defense this late in the season? Since the All-Star break, his defensive rating is 117.3. Only LaRavia is worse, at 119.0 (minimum 15 minutes per game).
Before the All-Star break, DeRozan came in at 113.8, a lot more acceptable. As a team, the defensive rating was 114.3 before the All-Star break (20th). Since then, it has been 116.5 (19th).
