It is hard to point out flaws of a team that is 13-0 after defeating teams like #1 Kentucky, Michigan and Ohio State, but if you look close enough, you ail find a few with the UCLA Basketball team.
The biggest concern is defense. In their last non-conference game against Western Michigan, the Bruins allowed (yes, allowed is the best word to describe it) the Broncos to drive and penetrate the lane over and over.
UCLA also allowed several wide open shots from the outside. Time and again, the Bruins would not close out or play their opponent close, allowing them a ridiculous amount of shots from behind the arc.
