We’re down to the Sweet 16 – and tonight’s brackets are full of top-seeded teams, because they’ve prevailed in the South and West brackets, with no team ranked lower than No. 5. Half of tonight’s action takes place on CBS, beginning at 7 p.m. ET with No. 2 Villanova vs. No. 3 Miami (FL), followed at 9:30 p.m. ET by No. 1 Kansas vs. No. 5 Maryland. Over on TBS, the action begins at 7:15 p.m. ET, with No. 2 Oklahoma vs. No. 3 Texas A&M. Then, at 9:45 p.m. ET, it’s No. 1 Oregon vs. No. 4 Duke. The other eight teams play tomorrow night, split again between CBS and TBS.
