*Note: All data is from the 1985 tournament to the present.

Last year’s tournament almost saw a historical mark when three No. 6 seeds fell in the opening round. If it weren’t for Notre Dame handling No. 11 Michigan, it would have marked just the second time in the history of the NCAA tournament that all four No. 6 seeds fell to No. 11 seeds.

The first and only time that happened was in 1989, when Kansas, Georgia Tech, Alabama, and Oregon State all failed to make it past the round of 64. Aside from this outlier, the No. 6 teams have a fairly successful 82-46 record against the No. 11 seeds over the past 32 years.

No. 8 No. 16
That doesn’t mean the games aren’t exciting. The margin of victory is only 3.1 points per game for the 6 seed, and more than 60 percent of the 6-v-11 games have been decided by 10 points or fewer. The sixth-seeded teams also have swept the opening round just five times since the tournament moved to 64 team format (1987, 1992, 1997, 1999, 2004). Over the past seven tournaments, however, the scales are tipping towards  the No. 11 seeds, who are 15-13 in that period.

No. 6 seeds are 1-1 in the national championship game since the tournament expanded to 64 teams in 1985 with the Kansas Jayhawks winning in 1988. Kansas avoided upsets from No. 11 Xavier, No. 14 Murray State and No. 7 Vanderbilt in the first three rounds.

Speaking of Xavier, the Musketeers have been involved in the 6-v-11 opening round a grand total of eight times, five times as the No. 6 and three times as the No. 11. Xavier has never won as the No. 11 seed but has a 3-2 record as the sixth-seed. However, the game most associated with Xavier as the No. 6 seed is the double overtime thriller against No. 2 seed Kansas State in 2010 Sweet 16.
