March Madness 2012 Bracket: Cinderellas Who Could Ruin Your Bracket in Sweet 16

This year's NCAA tournament still has several Cinderella teams left fighting to make a historic run to the Final Four, similar to what Butler and VCU did in recent seasons.

Since there's a number of lower-seeded teams left in the tournament, many of our brackets have already been busted. Meanwhile, for those lucky people whose brackets have yet to be busted, this week's games could still be trouble.

Let's look at three Cinderellas who could ruin your bracket in the Sweet 16.

No. 13 Ohio

The Bobcats are the biggest Cinderella left in the tournament after defeating Michigan in the second round and South Florida in the third round.

Against North Carolina in the Sweet 16, Ohio could ruin a ton of people's brackets by knocking out the talented Tar Heels.

With North Carolina starting point guard Kendall Marshall dealing with a right wrist injury (he shoots lefty), the Tar Heels will be weaker than normal, which gives the Bobcats a better—but still slight—chance of an upset.

No. 11 North Carolina State

The Wolfpack are feeling very confident after an impressive performance against No. 3 Georgetown in the third round and truly think they can defeat the No. 2 seeded Kansas Jayhawks.

North Carolina State has many players who can consistently score and present several challenges for the Kansas defense.

The Jayhawks have struggled against inferior teams over the last two years in the NCAA tournament, and have been inconsistent over the last month.

Don't be surprised if the high-scoring Wolfpack upset Kansas.

No. 10 Xavier

Xavier has a high-scoring team and a strong bench with Tu Holloway giving the Musketeers a 20-plus point scorer as a sixth man.

Against No. 3 Baylor in the Sweet 16, they just have to play well on defense and they have an amazing shot at an upset. 

Baylor is so inconsistent that it has become very frustrating for their fans. In one game they might look like they could defeat anyone with ease—next thing you know, they look like a bubble team.

If star forward Perry Jones III doesn't dominate offensively, the Bears will have a tough time defeating Xavier and advancing to the Elite Eight.
