If he's healthy he would possibly be our most talented player. That's a big if though, see for example that before the season many would have thought the same about Anton Gill.
As I understand it he would be eligible after the first semester was over, and getting a redshirt granted this year would only determine if he had an extra year after next season.
Would he give us anything we don't have already in Morrow, Roby, Jacobson and Horne, and maybe McVeigh? If he's 100% he'd probably be close to any of those guys in terms of doing what they do best, but all in one player. But having a guy come in after ten or so games and redistributing minutes at that point might be disruptive. So it would be a gamble, but if he does want to come here you definitely take him and work those things out later.
