What does Super Bowl winner Rob Gronkowski do in the off season? He rages his face off… And his shirt off. <br /><br />The NFL star is on stage with Meek Mill and Carnage at Ultra in Miami, taking full advantage of the music festival’s wild atmosphere. <br /><br />Gronk hasn’t seem to let himself go at all during his time away from the practice field, and proudly showed off his moves for everyone in attendance. His reputation as a party boy has not subsided. <br /><br />We wonder what his straight edged coach, Bill Belichick, would think of his antics on stage… But thankfully for Gronk, he doesn’t have to report for practice anytime soon. <br /><br />Oh, who are we kidding? As long as Gronk stays healthy and keeps winning, he can do whatever he wants. Shirts are optional. <br /><br />Keep on raging, Gronk. You only have five more months till football camp kicks off again. <br />
