03/21/16: Everything from the best opening tournament weekend ... ever?

The NCAA Tournament is underway ... and Gary Parrish, Matt Norlander and Sam Vecenie discuss the craziness from the first week. Everything from Northern Iowa's buzzer-beater to Northern Iowa's collapse. And Wisconsin's buzzer-beater. And Middle Tennessee's win over Michigan State. And Indiana's win over Kentucky. And Stephen F. Austin's loss in the Round of 32. And they close by turning their attention to some high-profile Sweet 16 matchups -- among them North Carolina-Indiana, Oregon-Duke and Kansas-Maryland.
