I've never particularly liked the diving timeout. Yes, it's a hustle move, which is good, but it's also a play that changes the game signficantly. It looks like the NCAA will do away with it this year:
Larry Keating, men's basketball rules committee chairman, said Friday that the timeout proposal stemmed from concerns about the difficulty officials have determining whether timeouts were called, the potential for injury and the unfair advantage it creates when players use timeouts to avoid turnovers.
"With players holding the ball with two hands, diving out of bounds, there's some risk of injury," he said. "The NBA had that problem four years ago and dealt with it. I just think it was something that everybody wanted to see and we were willing to do it."
