He's very athletic and only 23. Sounds good. As far as the roster size, I don't think we can judge this in a vacuum. There will be other moves this summer, maybe this week. And if not, we bought a 2nd round pick, that was acquiring with cap space from simple cap maneuvering, i.e. not signing Crowder yet/Lee trade agreed but not finalized.
Ainge/Zarren always sweatin' it, trying to be ultra-efficient with their handling of the cap, and squeeze out assets where they can. Not every front office does this. For this, I give them tremendous credit.
