No 16-seed had ever beaten a 1-seed in the men's NCAA tournament until 2018. Now it's happened twice.
In the first 28 tournaments that featured 15-seeds (1985-2012), four 15s had beaten 2-seeds. Seven have done so in the past 11. No 15-seed had reached the Sweet 16 until Florida Gulf Coast did it in 2013; now it has happened for three straight tournaments, and Princeton is one win away from putting a No. 15 in the Elite Eight for the second straight year.
The Sweet 16 will not feature any of Kansas, Duke, North Carolina or Kentucky for just the fourth time in 70 years .
