It's Down To Only One Perfect Bracket In ESPN's NCAA Tournament Challenge

Of course there was only a 1 in 9,223,372,036,854,775,808 chance of picking a perfect bracket, and yet, one person remains as the lone hold out.

After No. 11 Dayton beat No. 6 Providence in an upset on Friday, ESPN reported that it dropped to just one perfect bracket in its NCAA Tournament Challenge. You can check out that lucky entrant's bracket here.

And prior to Dayton's win? There were only six perfect brackets. While Friday brought more expected results (Dayton was the only lower seeded team to win from Friday's games), Thursday's upsets knocked out the majority of brackets, over 11.5 million, actually.

Although with plenty more games ahead, the biggest hope for perfection at this point is a 40-0 season from Kentucky.
