Honestly, I don't think they need him (though I don't think we need him either).
They have a nice 3 man rotation of Adams, Ibaka, Collison, and McGary. I think they're better with Adams starting instead of Kanter. They don't need Kanter's offense if KD is healthy and they just get much worse defensively.
Reggie Jackson was going to leave. They turned him into Kanter. If Kanter leaves, well they didn't lose anything they weren't going to lose anyway.
I don't think a guy who can't play defense on a max contract with a big trade kicker is a great "tradeable asset."
I assume they still have an MLE exception to sign a player if they are over the cap.
As a blazer fan and OKC hater, I hope they keep him.
If I were an OKC fan, I'd probably hope they didn't.
