I would seriously consider that. IT/Okafor could possibly be the best below-the-rim P&R combo in the league. We'd likely have to trade Sullinger, who I like more than most on here, as he doesn't fit defensively with Okafor at all. If we could get an athletic stretch 4 (tall task, but not impossible) with some combination of Sully, our 1st rounders last year + James Young, some 1sts (basically, our leftover assets, which would still be a lot), or Jordan Mickey becomes that guy (an even taller task, but also not impossible), we'd really be set:
IT
Smart/AB
Crowder
[Athletic Stretch 4]
Okafor
+ whatever is left of Sullinger, Rozier, Hunter, Young, Mickey, 2016 DAL 1, 2016 BOS 1, future owned 1sts, boatload of 2nds, etc.
