If Nash doesn't start I'm willing to bet you will have a chemistry problem with him. He needs to start and get 30+ a night or I think his effectiveness will be very little due to his ego. Unless he grows up a lot in the next few months I believe he will be carrying a big ego with him in Stillwater.
The good news though for Poke fans is he isn't going to be that undersized at 4. He's a legit 6'7 and I would guess in the 230 range, and is just strong. In college that will work, how many teams in the Big 12 are honestly going to have that much bigger 4s?
To go along with his strength he's also got some quick feet, he could be a prototypical face up 4 in college. He's big enough to not be much of a mismatch in the post on defense. If Ford gets him to buy into playing defense and crashing the boards on defense he will have a special year. If not, I think it could be a situation similar to Tiny Gallon had as a freshman. Probably better overall as he won't have weight issues, but he'll tease with flashes. Especially in the big games with the scouts watching but overall he'll end up leaving with OSU fans wanting just a little more from him.
