2023 March Madness: How to bet on the Sweet 16 after a busted bracket

So you ripped up your bracket around 5:30 p.m. Thursday when your champion Arizona went down to Princeton. Or maybe later Friday when 16-seeded Fairleigh Dickinson knocked off top-seeded Purdue? Join the club. Now what? Fortunately, there are still plenty of ways to have some action on the remainder of the men's NCAA tournament.

Let's start with second-chance Sweet 16 bracket pools. ESPN has one right here. Looks a lot easier with 16 teams left.

Or maybe you want to try a bracket pool with spreads? Find 16 people to fill a capture bracket. Everyone gets one team, and winners advance based on the ATS result. Your team could lose but cover the spread and you "capture" the other team.

Or you could throw the 16 remaining teams into an auction-style draft in which you buy teams with real money and pay out to the Final Four teams, finalists and national champion. It's a different form of the standard bracket pool and can be a lot of fun.

And then, of course, you could just wager on the games. Find a money line or spread you like and place a wager. Pregame, props or even in-game wagering are all offered for the final 15 games. Did you miss a future before the tourney started? You can still bet any of the 16 teams right now to win the region or title.

The story of the 2023 NCAA tournament has been big underdogs winning and unders cashing. For the first time since the field expanded to 64 teams in 1985, two underdogs of at least 15 points have won outright. FDU (+23.5) pulled off the biggest upset in the 64-team era, beating Purdue. Princeton (+16.5) also beat Arizona.

However, the most profitable play in the tournament has been to take games to go under the total. Unders are 35-17 so far in the tournament (.673), continuing a trend of unders hitting in the dance. Over the past five tournaments, unders are 182-134 (.576).

Houston entered the tournament as the betting favorite, but entering the Sweet 16, Alabama has surpassed Houston as the favorite. According to SportsOddsHistory.com, Houston is the first pre-tournament favorite in over 15 seasons to lose its favorite role entering the Sweet 16 despite not being eliminated.
