Cauley-Stein would have been excellent next to DeMarcus, but I wouldn't mind Clint Capela. 7th is a bit rich, though, and I happen to think there's some depth in the mid-card here where I wouldn't mind splitting the 7th into a mid-1st rounder and another pick. I have Capela 13th. When you see a Serge Ibaka variant, you jump and ask questions later, usually. Those are rare to get in free agency, so the best opportunities might come from the draft. Jokic and Nurkic are groundbound efficient types, and while I love their games, not for this team.
I also think we need a floor spacing four man because I'm of the belief that Rudy fits best at the high and DeMarcus at the low post, so there's that option. And no, Doug McDermott isn't an option. Not with the defense we have (not to mention that McDermott is one of those top 20 guys well--let's just lump him with Jerami Grant in my list). I like Adreian Payne more than my mock does, so I'll give him that benefit of the doubt, but he's a 20s pick and that requires a trade down. I'm not totally sold on Payne--he's grown a ton, but I don't think he has quite the ball skills to really make fulfill what people expect him to do in the league. Frye and David West, for starters, had far better assist rates coming out of college. But the guy has built a foundation of at-rim finishing, mid-range jumper, (possible) three point shooting, good free throw shooting, some shotblocking, and defense, that you really can't ignore him.
Ben McLemore by and large had a disastrous rookie year, and I know we've been having that Smart conundrum. I happen to be pro-Smart. He's not an uber athlete, but hey, for a 6'4" guard, dunking on 4.3% of your shots is right on average with most NBA SGs, so he isn't awful. The only thing is the Josh Smith-type jumpshooting-binging, but hey, that isn't stopping Aaron Gordon. I like Dante Exum a ton too (4th in my mock), so I'd be happy with either Smart or Exum. If we split down, go for Jordan Adams. Like the guy, but we need better passers, as a ton of Adams' shots are assisted. We have dunkers in Cousins and Gay and McLemore, so Adams 0 dunks this year won't be a problem.
