If you don’t like college basketball, it’s a good day to take a break from TV. (I’m doing my taxes today, so my TV is off anyway – except for the Gator game.) But if you’re into March Madness, you’ve already seen an upset, and today’s the start of second-round play, when upsets traditionally are even more likely. Today, three networks, not four, provide coverage. At CBS, LSU vs. Maryland starts things off at noon ET, followed on the same broadcast network by three more games: Kentucky vs. Wofford at 2:30 p.m. ET, Michigan vs. Florida at 5 p.m. ET, and Michigan  vs. Minnesota at 7:30 p.m. ET. On cable, coverage begins at 6 p.m. ET on TNT, with Florida State vs. Murray State, followed at 8:30 p.m. ET, on the same network, by Purdue vs. Villanova. TBS also has two games on tap: Gonzaga vs. Baylor at 7 p.m. ET, followed at 9:30 p.m. ET by Kansas vs. Auburn.
