UCLA could do some major damage this season. Their weakness though is a lack of depth as they really only have 6 guys who do much. After Ball, Welsh, Holliday, Hamilton, Leaf, and Alford they don't have much to speak of. If those 6 guys can remain healthy and keep playing the way they have though, I suppose anything is possible.
I think the x-factor for them could be how freshman Ike Anigbogu progresses. If he can become an impact big man off the bench to spell for Welsh/Leaf, they'd be in great shape.
