"Rob Gronkowski is one of the best tight ends in NFL history and he plays the game with the type of passion and desire that sets him apart," said Buccaneers general manager Jason Licht, via the team website. "Rob has played his entire career alongside Tom Brady and their accomplishments speak for themselves. Together they have developed the type of chemistry on and off the field that is crucial to success. Rob combines elite-level skills as both a receiver and blocker but what really makes him special is the fact that he's a proven winner who brings that championship mindset and work ethic."
