Tonight’s regional finals, broadcast live by CBS, are two games that have one at least one major thing in common: Both games feature the two top teams in their quarter of the tournament bracket. At 6 p.m. ET, it’s No. 1 Oregon vs. No. 2 Oklahoma in the West regional final. Then, at 8:45 ET, it’s No. 1 Kansas vs. No. 2 Villanova, in the South regional final.
