Where are we getting more of either?
Amir doesn't get many more blocks than Bass, and he's not much of a three point shooter.
Jerebko and Crowder were already on the team.
Rozier may or may not be able to shoot.
Young and Hunter are good shooters in theory; might not break into the rotation at all, and who knows if they can actually hit shots at the NBA level.
I think the Celts would like to maximize threes and hustle stats, but the moves to this point are far from guaranteeing it.
