Last night, one of the No. 1 seeds, the favored Kentucky, trounced its opponent, West Virginia, almost to the point of involving the college equivalent of the mercy rule. The other No. 1 seed playing Thursday, Wisconsin, had a much tougher time of it – and, in fact, was behind coming into the closing minutes, when it dominated play at the end and emerged victoriously. So, for the record, did No. 3 seed Notre Dame, getting deeper into the NCAA tournament than it has in a long time, and No. 2 seed Arizona, beating Xavier. Tonight’s coverage begins at 7 p.m. ET on CBS, with South’s No. 2 Gonzaga facing the tournament’s only remaining double-digit seed, No. 11 UCLA. At 7:30 p.m. ET on TBS, East’s No. 4 Louisville faces No. 8 N.C. State. At 9:45 p.m. ET, South No. 1 seed Duke takes on No. 5 Utah on CBS, and the night’s fourth and final game, presented by TBS, starts just after 10 ET, with East’s No. 3 Oklahoma facing No. 7 Michigan State.
