I question whether you could get an SGA for a Donovan Mitchell? GM’s aren’t stupid particularly Sam Presti, I’m sure he’s well aware of Mitchell’s ineptitude in clutch time. Anyway, I’m pretty certain that SGA is the one piece that Presti won’t trade.
Other than that, I agree that moving the one piece is superior to blowing up the team. The Knicks would probably be more inclined to do a deal. Fournier and Barrett for Mitchell works on paper. That deal makes sense to me and with our surfeit of guards could also make Conley expendable if coach is willing to give Butler and maybe NAW a shot.
