Given neither of those teams would have anything other than the MLE to offer (assuming there is a MLE which I doubt there will be) I would not be so certain.
I could see the twolves give him a pretty big offer
However, in the original post I said while I doubt it would ever happen, I would seriously consider the movewith tough, respected, veteran players in the locker room (Reggie, Posey, and JJ as an enforcer) and a veteran head coach who is widely respected.
Given what happened with Turkoglu, JR would chew JT up and spit him out.
But, again, I do not think this ever happens but if I were in charge I'd consider it. If JR joins a team with his head on straight and he works to his full potential - wow. Of course, if he continues being JR then buyer's remorse will surely follow that team.
