This might turn out like Ebuka Anyaorah's situation. By waiting until the end of his basketball year, Kemp might get a ton more offers.
It could also work out to UGA's favor. If Kemp really is unsure about going out to Seattle, he might want to stay home. In the meantime, Georgia could get more clarity on the number of big men we will have on the roster.
As I've noted in the past, Kemp has incredible upside. He will get more aggressive as he learns to play the game and as his body fills out some. See Roy Hibbert.
