I agree with most of this, you got Exum that high? I prefer Randle to Smart myself, really don't like his play for some reason.
Truth be told, I don't watch much college ball (didn't even know my school made the tourney until I filled out my bracket), so I'm basing a lot of this on the ceiling/floor comparisons, and scouting mixes. Probably very, very dangerous, since they're saying Embiid=Hakeem, Exum=Jordan, Wiggins=Pippen/TMac hybrid. Smart got some Wade comparisons, so the same thing with him.
I do think Randle (along with Parker, who BTW could **** us if he doesn't declare since both Randle/Smart will be off the board before we pick if he stays) is more NBA ready, so he could be useful if we want to try and go on a run these last two years of Kobe. Something like:
Gasol (resign for cheap, or Jordan Hill)
wouldn't contend, but it'd be a solid team to watch. With Smart instead (though he's more of a project I understand?), maybe Bosh (if he opts out) instead of Deng, and play Kobe at the 3 since he won't be as mobile.
