Never make a promise you can't keep.
After the Duke Blue Devils won their fifth college basketball championship on Monday by defeating the Wisconsin Badgers, Dallas Cowboys quarterback and Duke superfan Tony Romo placed himself in a bit of a quandry.
In a gentlemen's agreement captured for eternity on Instagram, Romo made a deal with Duke star Jahlil Okafor in 2014: if Okafor wins a national championship then Romo would need to win a Super Bowl.
Romo led the Cowboys to the playoffs last season, so next year it's Super Bowl or bust. Time to pay up, Tony.
