Probably the most awkward and awesome moment from the NCAA Slam Dunk Contest involved Jimmy Dykes, who hopped in to help out Kenny Gabriel. The dunk itself wasn't too bad, but it was the celebration that stole the show. Dykes and Gabriel shared a flying chest bump, with the former ending up on the floor because of the latter.
Dykes doesn't seem to have much in the way of ups. Got about six inches off the ground there. It's the effort that counts, though.
