I saw a few Vandy games on TV this year, and Foster's shooting really impressed me, especially in tough situations and big games. His defense didn't really stand out though, so I don't know how well he would fare against NBA SGs or SFs, especially the more athletic ones. He really can hit any shot on the floor though.
Another guy I saw a little of and really liked was Jamont Gordon, SG from Miss. St. He probably won't be available in the second round because his stock is really rising, but everyone is saying good things about him.
