*Note: All data is from the 1985 tournament to the present.
After the tournament expanded to 64 teams in 1985, it took six years before a 15 seed knocked off a 2 seed. Richmond beat Syracuse in 1991, 73-69. And every couple of years, a 15 seed shocks the college basketball world with a crazy upset. After a 10-year drought without an opening-round win by a 15 seed, they have won four first-round games in the last seven years.
But don't let that trick you into thinking the 15 seed has a good chance — they're 8-128 all time against 2 seeds.
The most recent shocker came when No. 15 Middle Tennessee never trailed in 2016 on the way to upsetting No. 2 Michigan State, 90-81.
The 2012 NCAA tournament was particularly volatile for the No. 15 vs. No. 2 matchups, as lower-seeded Norfolk State and Lehigh grabbed impressive wins in the first round on the same day. After a decade of smooth sailing for second-seeded teams, Norfolk State eked out a win over Missouri and Lehigh built up enough momentum to beat Duke by five.
While the 15 seed sports a winning percentage of 0.059, roughly 25 percent of the matchups heading into last year's tournament were decided by single digits.
Only one 15 seed has advanced past the second round, when Florida Gulf Coast made it to the Sweet 16 in 2013. In only its second year of full NCAA eligibility and first in the NCAA tournament, the Eagles shocked the college basketball world by not only beating second-seeded Georgetown by 10 points in the first round but also beating seventh-seeded San Diego State to advance to the Sweet 16.
Louisiana Monroe and Belmont own the most No. 15 seed appearances, as both the Warhawks and the Bruins have four berths at that slot in the 32 years of the expanded tournament.
