This sounds like a situation where the Cletics will trade him, but only if they get the offer the want.
This is what I've thought all along. They aren't shopping him, just listening. The original Woj reporting said as much. It was essentially "if they have to or will look to make a big move, this is the guy in their young core they will look to move". They just frame it as more with the headline and all because that sells ads and clicks.
Given his contract that makes sense. I think Ainge is still very high on him, and should be. Again, I don't know what will happen with his contract but I don't see much incentive to trade him unless there is some great deal to be had he could be a part of.
As far as the talk of where he fits as a rotation guy, the bottom line for me is he is one of the best defenders in the league so he impacts a game that much when he plays. When you're that good on defense there's always a good reason to try to develop a guy on offense more who has those abilities.
There's no question that money is about to get tight and even as a Smart fan it's tough to deal with that. Bringing in young players with picks will become essential in my opinion, to keep the team talented deep through the roster.
