Biggest College Basketball Postseason Upsets

Last Wednesday in the American East Tournament, Hartford defeated Albany in one of the biggest upsets of the season. The seventh-seeded Hawks, who finished the season with a 9-22 record, closed as 18.5-point underdogs against the second-seeded Great Danes (24-7). Many sportsbooks didn’t bother posting a moneyline, but Hartford closed at +3750 on the moneyline at Pinnacle.

Hartford went on to win by 9-points, resulting in the second biggest moneyline upset of the season trailing only Western Illinois (+6500) unthinkable victory over Wisconsin back in November.

Clearly this was an unbelievable accomplishment for Hartford, but we wanted to know how it stacked up against some of the all-time upsets. To accomplish this, we chose to comb through our historical database to find the biggest postseason upsets of all-time.

Note: Our archive dates back to the start of the 2004-2005 college basketball season.

Tournament Date Underdog Favorite Underdog Line Score
American East Tournament 3/2/16 Hartford Albany +3750 68-59
NCAA Tournament 3/16/12 Norfolk State Missouri +2250 86-84
WAC Tournament 3/14/13 Texas State Denver +1139 72-68
Pac-12 Tournament 3/8/07 California UCLA +1040 76-69
WAC Tournament 3/10/05 Boise State Nevada +1030 73-72
NIT Tournament 3/16/10 Jacksonville Arizona State +1025 67-66
Conference USA Tournament 3/10/05 South Florida Cincinnati +992 80-68
NCAA Tournament 3/19/15 UAB Iowa State +991 60-59
Big Ten Tournament 3/13/14 Northwestern Iowa +929 67-62
NCAA Tournament 3/18/10 Ohio Georgetown +925 97-83

As you can see, Hartford’s victory actually ranks as the biggest upset in college basketball postseason history. The second most surprising result came almost four years ago when 15-seed Norfolk State knocked off 2-seed Missouri in the first round of the NCAA Tournament. This is one of just seven instances in which a 15-seed defeated a 2-seed.

Readers may be interested to know that moneyline underdogs of +900 or greater have won just 4% of their postseason games over the past decade plus, but that doesn’t mean that bettors should be hammering these massive moneyline favorites. In these lop-sided games, the favorites have gone 239-10 (+1.25 units won) overall and, quite frankly, the risk simply is not worth the reward.
