UNC has a 1 in 142 chance of winning the title. KenPom is putting UNC's probability of making the Sweet Sixteen at 54% which is a perfectly reasonable win probability for the Tar Heels facing the #29 team in KenPom on a neutral floor. After that the numbers take a dip with UNC having just a 19% chance of making the Elite Eight and 6.7% of getting to Indianapolis. Given UNC's seeding and what we know, anything beyond the Sweet Sixteen will be beating the odds. Of course UNC did just that in Greensboro though the Heels were actually favored to beat Notre Dame and didn't.
Obviously Kentucky is the odds on favorite to win. The Wildcats has a 33% chance to taking the title. Kentucky is over 60% to advance to each round until the Final Four when the Wildcats have just a 46.1% chance of making the title game.
If you are wondering which team has the worst shot at winning the NCAA Tournament it is Hamption which has just a 0.3% chance of winning in the first round. Hamption's odds of winning the title? 1 in 932,647,504. No one is remotely that far out but that is probably because Hampton is in Kentucky's region and even if the Pirates get past Manhattan in the play-in game, it has no chance to beat the Wildcats.
