In these second-round March Madness games, it’s always fun to seek out the surviving double-digit seeds. They’ve already defied the odds, and their higher-ranked opponents, by winning their first game – and now, emboldened by that success, have the opportunity to score another bracket-bending upset. Today, that possibility exists with the first televised game of the afternoon, when CBS begins coverage with its noon ET broadcast of No. 2 Tennessee vs. No. 10 Iowa. Other games continue all day, with TNT joining the action at 6 p.m. ET, TBS at 7 p.m. ET, and truTV at 7:30 p.m. ET. The other contests with double-digit underdogs? In the opening TBS game at 7, No. 4 Virginia Tech plays No. 12 Liberty. In TNT’s second game at 8:40, No. 3 Houston faces No. 11 Ohio State. And at 9:40 on TBS, it’s the battle of the double-digits: No. 12 Oregon against No. 13 UC Irvine.
