I'd still take Diop over Mihm (Lakers), Blount (Wolves), Perkins (Boston). I think him and Sammy (Phi) are about on par, with Delambert having the slight edge, and that leaves Z as the only guy above him for sure.
But I think the only reason you'd take Diop is because of his age + salary.
If Blount didn't get a fat contract he'd be just as valuable. The same with Mihm. Perkins is probably on par with Diop except he's more offenmsive minded.
I'm not saying the other guys are "better." But it isn't Diop's skills that makes him better than those other guys. It is because he's only 23(?) years old and has a small contract compared to his production.
