BYU is 117th in points per 100 possessions. That's not good, and that factors in pac of play. I would say, in defense of Rose though, he has succeeded as a basketball coach with his currently philosophy so there probably isn't a huge reason to change it. BYU looked good on D in spurts v SDSU, which is a win for us, and else wise really has just kind of been having fun with the other competition.
