Once again, CBS and TBS share duties televising today’s Sweet 16 games. And tonight, there are no double-digit seeds left in the East and Midwest brackets, and the competition has advanced pretty much as predicted (though not without some buzzer-beating drama). In the East, for example, the four teams left standing are the top four seeds: No. 1 Duke (pictured) plays No. 4 Virginia Tech at 9:30 p.m. ET on CBS, while No. 2 Michigan State plays No. 3 LSU before that, on the same network, at 7. And in the Midwest, the rankings are nearly as tight: No. 1 North Carolina plays No. 5 Auburn at 7:30 p.m. ET on TBS, followed on the same network by No. 2 Kentucky against No. 3 Houston at 10.
