the only reason I would trade Mitch is the same reason as a Met fan I now want to trade DeGrom- and that would be to send him to a better franchise so his best years aren't wasted!
So - at this stage, no. I don't see any trade that makes sense to move Mitch given his contract, his upside.
The one criticism that maybe you could make of Mitch is he doesn't live and die basketball like some players do. But, I think that is ok.
