I know he has already been mentioned, but I think the player who will open the most eyes will be Elisha Justice from SV. I dont think people realize how great this kid is. He is a little undersized (5'11"ish) but has all the tools you look for in a guard. If SV can make a run, this tourney could serve as his coming out party.
Another kid from SV that I love watching is Taylor Newsome (#15, i think). He doesnt do a lot of spectacular things so he might not stand out to most people. But he is the perfect role player, the type of glue guy great teams need to have.
