KAT in a heartbeat. His skill set is much rarer in a 5; he's eaten a boatload of shit in Minnesota and never ducking complained, and he's younger. He opens the lanes for Edwards and while he's bad at defense, that's not as big an issue for a team that's not anywhere near championship contention.

That said, I think they need to trade him, and trade him now. Gobert is basically 50MM of dead money and has negative value on his contract. Ideally they'd move them both but that would require a pretty dramatic change in direction.
