Just 108 out of nearly 15 million brackets on ESPN remained perfect through the first day of March Madness

• Nearly every bracket was busted on the first day of March Madness.
• According to ESPN, of the 14.7 million brackets built, just 108 remain perfect through 16 games.
• The upset of No. 15 Oral Robert over No. 2 Ohio State was the biggest shocker of the day.

After a week of college basketball fans attempting to build their brackets to perfection, nearly every one of them was busted on the first day of March Madness action.

According to ESPN, of the 14.7 million brackets built on their platform, just 108 remained unscathed through the first 16 games of the men's tournament.

The brutal bust-fest was led by No. 15 Oral Roberts, who upset No. 2 Ohio State in the most shocking outcome of the day. With the win, the Golden Eagles became just the ninth 15-seed to pull off a first-round upset since the tournament expanded to a 64-team bracket.

Oral Roberts wasn't the only upset of the day. No. 4 Purdue fell to No. 13 North Texas in the South Region, and No. 6 San Diego State had no answer for the 2-3 zone defense of No. 11 Syracuse.

All told, five double-digit seeded teams stunned their favored opponents on Friday, making for one of the wildest opening days of March Madness in recent memory.

With just 108 perfect brackets remaining on ESPN, it's unlikely that any of them will make it through the second day of the tournament unscathed. But if you were bold enough to put through Oral Roberts over Ohio State, congratulations - you've earned bracket bragging rights for life.
