I am watching the UT vs TAM game. A foul was called when a player was tripped. The replay showed that the player stumbled and was not touched. This kind of call happens way too often in college BB, were a foul is called and the replay shows there was no contact. I think the refs don't see any contact, but assume contact must have happened. I would prefer that if the ref can't see contact, don't call the foul.
