How long did it take for a thrilling, buzzer-beating upset at this year’s tournament? The first day, when, during yesterday’s game between No. 6 South seed Miami Hurricanes vs. No. 11 seed Loyola-Chicago Ramblers, the Ramblers sank the game-winning three-pointer with 0.3 seconds left on the clock. March madness, baby! Today, once again, games are available on four networks, beginning at noon ET on CBS, 12:30 p.m. ET on truTV, 1:30 p.m. ET on TNT, and 2 p.m. ET on TBS.
