Not that surprising...
I saw Cal absolutely dismantle UNLV at the Thomas & Mack around Thanksgiving, and UNLV has wins against Arizona and Louisville to their credit, granted against Arizona they knocked down 14 3-pointers and when you do that, you'll beat just about anybody.
When Cal played UNLV, the two teams clearly had different levels of athletes, plain and simple. It was amazing to watch. Cal had a couple of ally-oop dunks that left the home folks with their jaws hanging.
