March Madness Betting Tips

The NCAA March Madness Tournament is always unpredictable! 

It’s one of the few times a year when sports bettors can really get in on the action and make some money. Here are some tips and strategies to help you make the most of your March Madness betting:

Place Smart Bets:

It’s important to do your research before placing a bet. Look at past trends, pay attention to team performances, and factor in injuries and other factors that could affect the outcome of a game. Doing so will help ensure that you are making smart bets that have the highest chance of winning.


If you’re looking for one key stat to predict which team will be cutting down the nets at NCAA tournament time, look no further than defensive efficiency. Since 2012, only one team ranked outside the top 40 in defensive efficiency has made it to the Final Four – 2018’s Kansas Jayhawks. The rest of that time period? Teams with the best defense have taken home a championship trophy every year.

Consider Match-ups

Looking at how two teams match up against each other can be a great way to gain an edge when betting on March Madness games. Paying attention to how different players are playing against each other, or how two teams have performed historically against each other, can give you valuable insight into which team might be more likely to win a particular matchup.

FG % Matters

If trying to compare all available stats for this March madness season seems impossible – consider changing up your approach and focusing on two stats instead: team field goal percentage and defensive field goal percentage. All else aside – teams making more shots (and making sure opponents miss theirs) are usually likely standouts come tournament time.

Set A Budget

It’s easy to get caught up in the excitement of March Madness wagering, but it’s important to set a budget and stick to it.

Ready to Place Your March Madness Bets?

We’ve reached the end of our comprehensive March Madness betting guide – it’s time to go out there and place your bets.

To sum it up, we’ll say once again that BUSR is the best bookie to bet on the NCAA tournament, offering the best March Madness odds and a sweet $2,500 welcome offer.

All that said, each online sportsbook on this list has something unique to offer, and you can’t go wrong with either one.
