Was this the best first day ever in an NCAA tournament? I’ve covered six of them, can remember 22, and this was the craziest. Eight of the 16 games went down to the final possession, the best being the Danero Thomas two-dribble buzzer-beater that lifted Murray State over Vanderbilt. Seven lower seeds won, the most improbable being No. 14 Ohio — the nine-seed in the MAC tournament! — knocking off No. 3 Georgetown in a game that didn’t come close to the final possession, because the Bobcats were dominant. It made for a phenomenal day of television. Keeping tabs on it from New Orleans Arena was its own form of madness.
