I'd actually really like to see him come to Boston, but I'd rather bring him here to play SF rather than SG.
We don't really have any shooting right now at the SF spot - Turner and Crowder are both pretty mediocre outside shooters. Bringing in Derozan in their place means we are gaining a lot (scoring ability, athleticism, etc) but not really losing much (since shooting is already a weakness there).
However if we traded him for Bradley and started him at SG, we then have a Guard and a SF who can't shoot threes...then you have Smart at PG and probably Sully of Lee at PF. That's some terrible court spacing.
A trade of Derozan for Sullinger, Turner and Perry Jones works according to the Trade Machine. Throw ina 1st rounder from next year, and that seems like a pretty solid return for Derozan (assuming Toronto are moving forward with Ross).
That would leave us with:
C: Amir Johnson / Tyler Zeller
PF: David Lee / Kelly Olynyk / Jordan Mickey
SF: Demar Derozan / Jae Crowder /Jonas Jerebko
SG: Avery Bradley / RJ Hunter / Terry Rozier
PG: Marcus Smart / Isaiah Thomas / Terry Rozier
Nice roster there - lots of versatility, lots of depth, and a very nice offense/defense balance.
