Before the 2017-2018 season, the answer would’ve been a resounding no, said Sports Illustrated. Sure, some teams have gotten very close. In 1989, East Region top seed Georgetown had a tough time holding off 16 seed Princeton. Georgetown won by a point. The same year, Oklahoma faced off against East Tennessee State and also won by one. Michigan State, the number one team in the Southeast Region, fought off Murray State in 1990 and almost lost.

But the records changed during March Madness 2018. According to Sporting News, the University of Maryland-Baltimore (UMBC) traveled to play the University of Virginia Cavaliers. The Cavaliers were not just the top seed in the region; they were the first seed in the whole of NCAA that year. UMBC, on the other hand, was not. SBNation even characterized UMBC as one of the worst teams in the tournament.

At half-time, the two teams were tied. Virginia seemed to control the game, and sports journalists fully expected the team to start dominating. But UMBC took their chances with three-point shots and began chipping away at Virginia. By the end of the game, 16-seed UMBC beat first seed Virginia 74-54 by 20 points and became the first team in NCAA history to win against the top team in the bracket.

So, think about that when you’re setting up this year’s bracket.
