Man's NCAA bracket blunder costs him shot at $50K prize

James KiKi is currently tied for first place out of more than half a million brackets submitted to Yahoo.

But, he made one fatal mistake.

He forgot to choose a national champion.

Yes, he's made it this far, getting most of the picks right.

But, since he forgot to fill in a winner, he has no shot at the $50,000.

Kiki says he would have picked Villanova, beating North Carolina for the crown.

Though, as a New Yorker, he's rooting for Syracuse.
