March Madness 2017 is almost over with four teams fighting for college basketball’s national championship. North Carolina, Oregon, Gonzaga and South Carolina will be in action Saturday night, hoping to advance to the NCAA Tournament title game Monday night.

The Final Four begins with the contest between No.1 Gonzaga and No.7 South Carolina at 6:09 p.m. EDT. No.1 North Carolina and No.3 Oregon have a scheduled start time of 8:49 p.m. EDT, but they’ll tip off 40 minutes after the first game concludes if it runs late. CBS will have TV coverage of both games, and the games can be seen with a free live stream online at ncaa.com.

North Carolina enters the Final Four as the favorite. The Tar Heels are playing in the Final Four for the 20th time in school history, and they’ve reached the national championship game three times since 2005. North Carolina was beaten in last year’s title game when Villanova’s Kris Jenkins hit a three-pointer at the buzzer.

If the Tar Heels don’t win it all, the NCAA will have an unlikely champion, at least when considering the history of college basketball. Gonzaga and South Carolina have never even played in the Final Four, let alone won the national championship. Oregon won the first-ever title in 1939, but they are in the midst of an 87-year championship drought.

According to Bovada.lv, the most likely outcome is North Carolina defeating Gonzaga Monday night. While that outcome has +230 betting odds, a win for South Carolina over Oregon is considered to be the least likely scenario with +1400 odds.

South Carolina and North Carolina both defeated No.2 seeds in their respective regions, while Oregon upset No.1 Kansas in the Elite Eight. Gonzaga’s best win in March Madness was a Sweet 16 victory over No.4 West Virginia.
