Texas A&M vs. Penn State (7 vs 10), Iowa vs. Auburn (8 vs 9), St. Mary’s vs. VCU (5 vs 12), and Michigan State vs. USC (7 vs 10) all bear watching as the result could sway one way or the other. Whatever you do, take advantage of one of these great March Madness bonuses so that you can win with each matchup on the slate.
