Daniel Wilco | NCAA.com | March 17, 2018 Looking at the worst brackets in the 2018 NCAA tournament UMBC upsets Virginia, 74-54 Share Marshall's major upset of 4-seed Wichita State took the number of perfect brackets across the world from a few thousand to just a couple hundred. But for two brackets in our Capital One Bracket Challenge Game, it was the first game they got right.

They also had faith in 16-seed Radford (lost by 26 points to Villanova) and 16-seed Penn (lost by 16 to Kansas). Unfortunately, one bracket (titled Mary May), which was was 0-for-16, slipped up and got Texas A&M's win over Providence correct in the 17th game of the tournament.
