Josh reminds me quite a bit of himself. I mean, it's uncanny the similarities.
Aside from that, what is the point? He's tall. Not a leaper, but arms are long enough. He has pretty good hands, and some decent post moves for a freshman. He's not a great rebounder, but some additional strength will allow him to hold his position better on defense and block-outs. I see some indications of shooting touch that should develop. He'd need a lot more bulk to back people down, I don't see that as his game. But it seems like he has some fairly deft spin/bank shots that he can use to good effect. If he can develop a face up jumper from 10', that would be big.
I'd like to see how he runs the floor. Haven't had enough of a sample size yet since our offense was so plodding. Lack of footspeed would be a limiting factor for him on this team, based on what I expect to see. I'm confident Diarra has wheels and can finish on the break. I think even Cobb can get out and finish (for how long I'm not sure). Whaley is built for that kind of role.
