ESPN's Tournament Challenge Has Just 1 Perfect Bracket Remaining out of 11.57M

There are 11.57 million entries in the ESPN Tournament Challenge this year. However, after just two days of the 2015 NCAA men's basketball tournament, only one perfect bracket remains.

Update from Saturday, March 21

After the Arizona Wildcats pulled out a 73-58 victory over the Ohio State Buckeyes in the round of 32 on Saturday, there are no more perfect brackets remaining in the ESPN Tournament Challenge.

Many brackets were busted during Thursday's wild round-of-64 games. Although Friday's slate of games featured just one upset, the number of perfect brackets left standing was narrowed down to one by the end of the night.

Through two days, user Malaquias4394 has the only perfect bracket remaining in the ESPN Tournament Challenge:

It's incredible to think that someone was able to predict all of these crazy upsets without stumbling once. No one accomplished that same feat in Bleacher Report's bracket challenge.

Here are the teams Malaquias4394 picked to go to the Final Four and win the national championship:

Having Duke beat Kansas, 58-0, in the championship game is certainly bold. Then again, this person has made plenty of bold predictions through the first couple of days of the tournament and hasn't faltered yet.
