It's not your fault your brackets are busted; there have been some truly remarkable upsets in this year's NCAA tournament. But some stand out beyond the rest of the pack.
Frankly, no one saw these upsets coming, and it would have looked foolish to pick them in your brackets...now who's looking foolish?
We were all caught with our pants down when it came to these games, and these are the Top 10 upsets that no one saw coming so far.
52 games down, 15 to go.
We knew that Oregon was underrated as a No. 12 seed, and we knew that the Ducks were hot after winning the Pac-12 tournament. However, we didn't know just how hot until the team took down Marcus Smart and Oklahoma State.
Arsalan Kazemi's double-double led the Ducks to an incredible 13-point rout of a tough Oklahoma State team that had a ton of potential.
While Smart still had himself a day (14 points, nine rebounds, four assists, five steals), Oregon was able to stymie the rest of the Cowboys to win 68-55.
UNLV was supposed to roll over California behind freshman phenom Anthony Bennett—but you can never tell who will win in a No. 5 vs. No. 12 matchup.
The Golden Bears had four players score in double-digits, led by Allen Crabbe's 19 points and nine boards.
The Rebels seemed like they could have beaten No. 4 Syracuse and advance to the Sweet 16, but they couldn't even get out of the Round of 64.
Never bet against Marshall Henderson.
Even when it looks like things are going wrong for the Ole Miss star, he finds a way to turn them around. After making just one of his first 13 shots, he scored 17 points in the final 11-and-a-half minutes of the game.
Wisconsin's stingy defense couldn't keep him from dropping a game-high 19 points, and the Rebels pulled away for the 57-46 victory.
Alex Kirk probably went into New Mexico's game against Harvard thinking that if he went for 22 points and 12 boards, his team would have to win. However, the rest of his teammates shot a paltry 12-of-38 from the floor (.316).
The Crimson only played seven guys, but Siyani Chambers, Laurent Rivard and Wesley Saunders played a combined 119 minutes.
Harvard shot an impressive 52.4 percent from the floor and 44.4 percent from three as it won the game by a final score of 68-62.
Rodney McGruder will never forget his final game of collegiate basketball.
The senior missed a three that would have put Kansas State up 64-60 with 31 seconds left in the game, and Jordan Henriquez fouled Jerrell Wright on the rebound. Wright made both freebies to put La Salle ahead 62-61, and missed shots from Henriquez and Angel Rodriguez sunk Kansas State's chances.
McGruder struggled, scoring just 13 points on 17 shots. His Wildcats simply couldn't handle a La Salle team that was led by Wright's 21 points and eight rebounds on 6-of-6 shooting from the floor. The result was a 63-61 win for the Explorers.
Last year's NCAA tournament was utterly ridiculous, as two No. 2 seeds fell to No. 15 seeds on the same day.
We got another taste of such a monumental upset this year when No. 15 Florida Gulf Coast pulled off another shocker, this time over No. 2 Georgetown.
After already beating Miami early in the year, Florida Gulf Coast took out one of the favorites to advance to the Final Four, led by Sherwood Brown and Bernard Thompson's 47 points.
The Eagles definitely pulled off the biggest upset of the Round of 64 this year, winning 78-68.
OK—I'll give you that No. 12 Oregon could upset No. 5 Oklahoma State...but No. 4 Saint Louis?
The Billikens had won 25 of their last 26 games that ended in regulation, including five against Top 25 opponents. However, Oregon went up 35-19 at the end of the first half and the Ducks never looked back.
Oregon is on fire right now, and after pulling off these two upsets we will see them challenge No. 1 Louisville in the Sweet 16.
Gonzaga was ranked No. 1 in the country and had won 15 games straight when the Bulldogs were knocked off by No. 9 Wichita State.
The Shockers did it again, shooting 14-of-28 from three to sink the Bulldogs.
Gonzaga had all the makings of a Final Four team, but now it will be Wichita State playing No. 13 La Salle in the Sweet 16.
No. 13 La Salle over No. 12 Ole Miss in the Round of 32 might not seem like a major upset...but it was.
Ole Miss was hot after beating Wisconsin by 11, and Marshall Henderson looked like he could become a tournament hero.
However, Tyrone Garland's layup with three seconds left gave the Explorers the win, with a final score of 76-74.
Anytime a No. 13 seed makes it to the Sweet 16, you know that's an upset...and you know it warrants its own slide on this list.
Including Florida Gulf Coast, seven No. 15 seeds have beaten a No. 2 seed in the NCAA tournament. However, before this year not one had been able to make it to the Sweet 16.
Welcome No. 15 Florida Gulf Coast to the Sweet 16. Considering that the school was letting any full-time student who had played high school basketball try out for the team (via Darren Rovell of ESPN), I'd say that's pretty Cinderella-esque.
With back-to-back double-digit point margins in their victories, the Eagles look impressive and will try to take down No. 3 Florida in Arlington on Friday.
