March Madness betting: North Carolina was 125-to-1 to win the tournament at the start – Yahoo Sports

March Madness is coming to an end. In fact, the Final Four will be played in April. However, we're still without a national champion. We are down to just four teams. One of Duke, Villanova, Kansas or North Carolina will capture the title, so let's take a look at how these teams got here from a betting perspective.

Right after Baylor won the championship game in April 2021, betting odds for the 2022 national championship were posted. Where did these teams find themselves?

Villanova (12-to-1)

Duke (14-to-1)

Kansas (16-to-1)

North Carolina (30-to-1)

Gonzaga opened as the favorite to win it all, but it bowed out earlier in the tournament. None of these teams were huge long shots when the odds got released. Villanova was tied for the third-best odds, and Kansas and Duke were not far behind. North Carolina was a bit further down, but it opened with the same odds as Michigan State and Virginia, two programs with a lot of recent success.

Once the season got underway, the odds began to fluctuate a bit. Let's take a look at where these teams stood on New Year's Day and on March 1, days usually associated with the start of conference play and the start of the postseason drama.

Villanova (22-to-1 on Jan. 1, 20-to-1 on March 1)

Kansas (11-to-1 on Jan. 1, 14-to-1 on March 1)

Duke (+800 on Jan. 1, 12-to-1 on March 1)

North Carolina (66-to-1 on Jan. 1, 125-to-1 on March 1)

The main team that sticks out here is North Carolina. The Tarheels were certainly inconsistent over the course of the season and many viewed the ACC as one of the lesser major conferences this season. Once late February and early March rolled around, many had UNC on the tournament bubble and didn't even know if the Tar Heels would get the opportunity to make this run.

Villanova, Duke and Kansas all stayed relatively consistent over the course of the season. Kansas finished tied atop the Big 12, Villanova finished 2nd in the Big East and won the conference tournament, while Duke was clearly the best team in the ACC during the regular season.

If you're more of a totals bettor, below are the over-under record for teams over the course of the season. Which teams' games are going over at the highest rate?

What have you done for me lately? How are these teams performing against the betting number in the tournament?

North Carolina (4-0, +63 margin of cover)

Villanova (4-0, +21 margin of cover)

Duke (3-1, +13 margin of cover)

Kansas (2-2, +18 margin of cover)

North Carolina and Villanova are 4-0 against the spread in the tournament. Duke is 3-1, with its one loss against the spread coming in its first round game on a relatively bad beat. Kansas is 2-2, failing to cover in wins over Creighton and Providence.

Let's take a look at how these teams are performing against the number from a totals perspective:

Duke is very close to a 3-1 over record, but bettors suffered a bad beat on Saturday night. North Carolina started with two games that flew over the total, but its last two games have gone well under. Villanova's last three games have gone under the total.

In the Final Four, Kansas is a 4.5-point favorite over Villanova. In the other matchup, Duke is a 4.5-point favorite over North Carolina in the first tournament meeting between the ACC rivals.
