Also consider some statistics, per basketball reference.
During the regular season, the Celtics eFG% was a significant 0.052% worse when Rozier was on the floor (vs. off the floor), and the offensive rating was 8.7 points worse.  That is... a tremendous difference.   The same was true in the playoffs.  The Celtics eFG was 0.049% worse, and the offensive rating was  6.6 points worse with Rozier on the court.  Not to mention he shot just 32% in the playoffs, including 24% from 3, while averaging a pitiful 3.9 assists per 36 minutes.
If you like Rozier and support him, that's fine.  I just don't quite understand why.  He's a malcontent who overestimates his abilities and he both visibly (eye test) and statistically makes our team worse when he plays.
By all means, get lost Terry.
