Rob Gronkowski Eats Extra Spicy Hot Wings & Lets His Tears & Snot Fly

New England Patriots tight end Rob Gronkowski has won a Super Bowl, earned a spot on the first team All-Pro roster three times, and was named the 2014 AP Comeback Player of the Year. But what does he say is the hardest thing he's ever done? The Buffalo Wild Wings Blazin' Challenge. For USA Today, Gronk participated in the feat, which traditionally consists of competitors downing a dozen of the franchise's hottest wings in under six minutes. The sauce is so hot, participants have to sign a waiver before competing.
