That's why I said Stauskas may not be the guy. But if there's a real concern about keeping Kanter, then at least get an asset. So trade him for a pick and an expiring if you don't want an extra contract. Personally, I'd take a top-10 pick like Stauskas. Shooters are extremely valuable. You could bring him in and split the minutes between him and Hood (sorry, Elijah). Either one can be an asset in another trade down the road. Makes much more sense than Kanter getting a deal for $10M+ and the Jazz then deciding not to match.
Perhaps if it weren't for the number of bigs in the draft, I might be inclined to say keep Kanter. Then again, that very fact might decrease his trade value...unless a team is desperate to do "something," which it appears is the current state of the Kings.
