The 11-6 March Madness Upset Isn’t an Upset

Sixth-seeded Vanderbilt trailed 11-seed Western Michigan at halftime of their first-round game in the 2004 NCAA Tournament. In the final 11-6 matchup of the first round, the Commodores rallied for a 13-point win en route to their first Sweet 16 since 1993. With the win, 11-seeds went undefeated in the first round for the first time since 1999 and just the fifth time since the tournament expanded in 1985.

Exactly 17 years later, 11-seed Syracuse defeated 6-seed San Diego State in the first round of the 2021 NCAA Tournament. The 16-point win guaranteed a 15th straight tournament with at least one 11-over-6 upset.

The seeds and, in most cases, NCAA Tournament odds – Vandy, for example, was a 1-point underdog against Western Michigan – say it’s an upset. And for the first 20 years of the current March Madness format, history said it was an upset. From 1985-2004, 11-seeds won 24 of 80 (.300) first-round games against 6-seeds. Over the last 15 tournaments, entering Saturday’s games, 11-seeds have won 29 of 62 games (.468) and raised their overall winning percentage to .369.

They’re a four-game winning streak away from evening the series since 2005. Or they’re another 2016-17-like run – when 11-seeds went a combined 6-2 – away from reaching .500. 

That upset isn’t an upset. In the same way Gonzaga is technically a mid-major per Jack Kvancz’s definition, but not considered a mid-major after two decades of dominance, the 11-over-6 upset is not an upset. Fifteen years ago, Gonzaga was an obvious mid-major, just like an 11-over-6 outcome was an obvious upset.

The 29 wins since 2005 have come by an average of 9.1 points. Sixteen have been double-digit wins, including one 20-point win by Minnesota over UCLA in 2013. Only 10 have been decided by fewer than five points
