If you still have a perfect NCAA tournament bracket, you're probably cheating

It only took two days of competition, but it looks like every single bracket in the world has been busted. With the help of massive underdogs Florida Gulf Coast and Harvard mounting major upsets, not a single perfect bracket remains in any of the major bracket challenges.

Have a bracket on ESPN.com? Better luck next year.

Ditto for CBS Sports (incredibly, the last perfect brackets were undone when Indiana beat James Madison).

At Yahoo, there isn't even a single bracket with just one incorrect pick.
