The NCAA will also stream games via its March Madness Live option. The top betting favorites as the tournament begins: Florida and Duke are listed as co-favorites (+325), according to BetMGM Sportsbook. Auburn (+425) and Houston (+600) are next.

The best the bracket has so far is a pair of No. 12 seeds over 5s. That's become almost expected — occurring at 35% clip, according to the NCAA — and one of them wasn't even an upset. Colorado State was favored by 2 1/2 points over short-handed Memphis, according to BetMGM Sportsbook, and the Rams won 78-70.

Madness has gotten off to an exciting start. South Carolina and Notre Dame both flexed their dominance with blowout victories, Kentucky survived an upset scare against Liberty, and Oregon became the first double-digit seed to advance with an overtime victory over freshman phenom Mikayla Blakes and Vanderbilt.
