I don't think Sledge should be discussed as a draft pick when he hasn't even played a game of college ball yet. It is not like he is Derrick Rose or Kevin Durrant. Look how good DG did this year and he couldn't get drafted.
I would say White probably has the most pro-potential on the team, if Allen has improved his PG guard skills then he could be a solid second round pick. Babb's height makes him a fit for the two guard in the NBA but he will have to show a lot more than he did at Penn State. If McGee can play the point well and can continue to shoot a high percentage from three he might have a chance of getting drafted.
