I dont think Kanter is a fit in Boston, like others have said not a rim protector and a bad fit next to Sully and KO on D.
I'm also not sure what the Jazz will want for him, I suspect a lightly protected 1st gets the deal done. He is a restricted FA so the team that makes the deal has to figure on paying him this offseason.
A few teams I could see making a play for him.
1. Miami, nice fit next to Bosh at 22 he would be their youth. Not sure they have much to offer.
2. Bucks, they have length and good defensive players an offensive minded big could be a nice fit.
3. Raptors, need to upgrade their big man rotation Kanter does that while also adding youth. Do they do a ross for Kanter swap?
4. Pacers, not sure if he is a good enough defender for their system but he would give them another option on O.
