The NCAA tournament kicks into its Sweet 16 phase, which makes things a lot easier to keep track of, and describe, and watch. Four games are played tonight – two on CBS, two on TBS – and four more tomorrow. The first game tips off shortly after 7 p.m. ET on CBS, when Stanford (seeded No. 10 in the South) faces Dayton (No. 11). That may sound like a dull contest, but it’s not: so far in this tournament, both Stanford and Dayton have battled higher-seeded teams in every game, and beaten them all, including Stanford beating No. 2 Kansas and Dayton beating No. 3. Syracuse. At 7:45 p.m. ET on TBS, Wisconsin (No. 2 in the West) faces Baylor (No. 6). At 9:45 p.m. ET on CBS, Florida (No. 1 in the South) faces UCLA (No. 4). And finally, at 10:15 p.m. ET back on TBS, another top-seeded team, the West’s Arizona, faces San Diego State (No. 4).
