2. Buffalo over Arizona

Raise your hand if you had Arizona going to the Final Four. If you’re like a quarter of fans who filled out a bracket, you likely had the Wildcats going deep in the NCAA Tournament — ESPN even had a stat that over 17 percent of people who filled out brackets on the site picked Arizona to win it all.

The Wildcats had a tough game against Buffalo as it seemed like the off-court distractions caught up to this team. It’s been a rough few weeks with an apparently misreported wiretap which caused Sean Miller to take himself away from the team for a game, but he was cleared and his team began to play for him in the Pac-12 Tournament.

Momentum seemed to be on the side of Arizona heading into the tournament, but the Wildcats got a tough draw in MAC champion Buffalo. The Bulls were slightly under-seeded, as many teams were, and gave the Wildcats all they could handle.

Buffalo didn’t just beat the Wildcats, they absolutely dismantled Arizona to the tune of a 21-point victory. Buffalo is going to be a team to watch in the round of 32 as their shocking run may not be over.

UMBC’s improbable win over Virginia is the only reason the Bulls didn’t get the No. 1 spot on this list.
