An NCAA men's basketball tournament that was expected to be dominated by favorites has lived up to its billing through two rounds.
In the West and East regions, all of the top four seeds advanced to the Sweet Sixteen. In the Midwest, No. 5 seed Houston pulled off the mildest of upsets, beating No. 4 Kansas in the second round.
There's only been one big-time bracket-buster through two rounds: The No. 12 Oregon men, who knocked off No. 5-seed Wisconsin in the first round and then beat No. 13 UC Irvine on Sunday to advance to the Sweet Sixteen.
