For the first time ever, all four Final Four teams enter having won multiple national championships. All four teams entered the year with 30-1 or shorter odds, with Villanova leading the way at 12-1, and North Carolina the biggest preseason long shot at 30-1.

North Carolina was a much bigger long shot entering the NCAA tournament. The Tar Heels were 100-1 during the First Four. If they cut down the nets on Monday, they would be the biggest pretournament long shot to win it all in over 25 seasons according to SportsOddsHistory.com.

Duke and Kansas enter the Final Four as the two favorites, and historically, one of them will likely win the national championship. In 16 of the past 17 Final Fours, one of the two favorites entering the Final Four went on to win it all, according to SportsOddsHistory.com. The one exception was in 2014 when UConn won it all.

Last weekend, 11 of the 12 Sweet 16 and Elite Eight games went under the total. Historically, there aren't significant trends to totals having different results in the Final Four. However, the last time the Final Four was held in New Orleans, all three games went under the total.
