Just 20 percent of the 8.15 million Tournament Challenge brackets picked 12-seed Ole Miss over 5-seed Wisconsin. Mississippi beat the Badgers, 57-46.

The Badgers were a popular pick to reach the Sweet 16 (54.7 percent of brackets) and they also were picked to reach the Final Four in 9 percent of brackets. President Obama had Wisconsin reaching the Elite Eight.

With this result, there are now just 349 perfect brackets remaining.
