I kinda get it. We'll renounce Rose, so we got rid of JJ which is nice for both parties.
Hood, in a vacuum, is a better player than Crowder. However, Hood wasn't going to get re-signed, and wasn't going to have a big role here. Hood will probably put up better stats in Cleveland just because of the role he'll have there. He's a good player.
Crowder is no slouch though. Good positional flexibility, good defender, good shooter, jack of all trade kinda guy. Great, great contract. Cleveland just wasn't a good place for him because Cleveland doesn't really run an offense. Boston, obviously did. We, obviously do. Snyder will help Crowder out a lot, imo. Last year Crowder put up 14/6/2 on 46/40/81 shooting splits. That's pretty darn good. I think last year a lot of us would have been willing to do a Crowder-Hood trade, and Hood arguably has less value now because he's a half year rental.
