Since the tournament field expanded to 64 teams in 1985, 17 top seeds have exited the tournament in the second round, while zero have yet to suffer an upset to a No. 16 seed. But that doesn’t mean they haven’t had a few scares.

Take the 1989 tournament for instance when not one but two No. 1 seeds (Georgetown and Oklahoma) barely escaped in the opening round. The Hoyas and Sooners defeated Princeton and East Tennessee State respectively by a single point. A year later, Michigan State found itself in a similar position before eventually defeating Murray State, 75-71 in overtime.

While no other teams have come down to a single possession, there have been some memorable games in the past five years that have been decided by single digits. Both 2012 Syracuse and 2013 Kansas survived tough contests from No. 16 seeds, defeating UNC-Asheville and Western Kentucky respectively by seven points.

Now, the No. 1 seeds may have it easy in the opening round, but the rest of the tournament could go either way. Despite the dominating numbers, 2008 remains the only year that the Final Four has been comprised of all No. 1 seeds. Only six title games since expansion have been a 1-v-1, including last year's showdown between Duke and Wisconsin.

The 2015 national championship came during Duke's 13th appearance as the top seed in its region. Thanks to the Blue Devils, the Atlantic Coast Conference has the most No. 1 seeds since 1985 with 27.
