So I’ll preface this post by saying this is entirely hypothetical. Yes, the roster is set. No, this would never happen. Just clarifying for the inevitable “ZOMG this ain’t happening lol” post.
That said, we’ve got a good team defense but could still use some individual specialists to throw at guys depending on the situation. Exum can be that guy, but I think he’s limited in that he can guard the smaller perimeter guys like a Harden and Curry, but is going to get outmuscled by the bigger guys like a Kawhi or PG. I’d move Exum and Bradley to OKC for Andre Roberson and Patrick Patterson. That gives us more size and shooting options at the 4, but gives you a guy who can body the LeBrons, Kawhis, PGs, and Giannises. He’s very limited offensively. Much more so than Exum, but he’s a really good defender, really strong, and I’d be thinking of utilizing him football style at the end of close games where you can sub out defensive and offensive teams. To replace what we’d lose defensively from Exum off the bench, I’d sign Iman Shumpert to a minimum deal. He’s not getting a ton of minutes, but him and Roberson are defensive closers in all those end-game defensive possession situations.
