Questions & Answers

The annual March Madness bracket pool has always been a popular way to bet on the NCAA Tournament. But anyone who’s ever entered an office pool knows those early-round upsets can bust the bracket in a hurry. Your entire Final Four can go up in smoke on opening weekend.

What then?

So maybe you had the Duke Blue Devils winning it all and they don’t even make the Sweet 16. Making actual bets on March Madness means you can keep a rooting interest in every single game. Those upsets are a lot sweeter when betting the money line on an underdog.

Bettors who watch college basketball games every night can also clean up. It’s not just Kansas and Michigan State in this thing. Those that have logged the hours with San Diego State and Belmont and Wofford should do far better on point-spread betting. March Madness odds are largely a reflection of seeding and public perception, so there’s tons of value for the true hoops nerds familiar with lesser-known teams.

Lastly, betting on March Madness is a blast. Watching the NCAA Tournament from morning to night is a glorious experience. Throwing a few dollars around with some Sweet 16 bets or longshot Final Four or championship futures takes the good times to another level.

With the continued expansion of states legalizing sports betting, you can now wager on March Madness in more states than ever before. The states that will have online operational sports betting ahead of March Madness are as follows.

  • Indiana
  • Iowa
  • New Jersey
  • Illinois
  • Tennessee
  • West Virginia
  • Nevada
  • Michigan
  • Colorado

Sports bettors develop systems and strategies for March Madness over time, many of which are unique to the NCAA Tournament and can’t be used in other sports. Take the seeding, for example. That is how the public will perceive these teams, more so than record or conference or past performance. March Madness betting is a great time to take advantage of public perception or consensus betting. A team could be overvalued based on past reputation, which is a great time to bet against them. Some teams are undervalued because the public hasn’t watched their games. Identify these teams and those betting lines and wager accordingly.

Moneyline betting on underdog teams is also a popular strategy. A No. 12 seed has upset a No. 5 seed 47 times since 1985. Remember these teams are seeded by human beings prone to errors of judgment. Betting the money line on a No. 12 seed you believe to be undervalued can be your one shining moment, with big profits and bragging rights.

One can also bet for or against conferences on the whole. Every season it seems a conference that’s been hyped up all year will see all its teams lose in the early rounds. Fading an entire conference with spread and money line betting on individual games is just one of many ways to attack March Madness betting with vision and strategy.

Betting on March Madness is legal and ready in several states, with each state having its own rules on sports betting. Those that have legalized sports betting in some form include Indiana, Iowa, New Jersey, Oregon, Pennsylvania, Rhode Island, West Virginia, Nevada, Arkansas, Delaware, Mississippi, New Mexico, Tennessee, Michigan, and Illinois.

An upset occurs when a higher-seeded team beats a lower-seeded team. A No. 15 seed could upset a No. 2 seed, for example. Upsets take place every year, and they’re a big part of the fun in betting on March Madness.
