How about just IT, Crowder, Sully, and our own '16 1st for Love? Sully is a better replacement for Love than Randle is. Better spacing, rebounding, and especially defense (Randle is really bad on that end). Randle has more theoretical upside, so we throw in a mid-1st rounder.
I think the C's have to do that even though it costs us our two best players. Love is a guy you can build around, and you gotta think that part of IT + Crowder's success has to do with Brad Stevens. I'd love to see what he can do with a guy as talented as Love.
I have little interest in Okafor. It's really tough to play a guy who provides neither 3 nor D. He needs to be in a perfect situation in order to thrive, surrounded with shooters, and we're not exactly hoarding marksmen on this team - especially if we trade IT away.
