Throughout his nine seasons with the New England Patriots, tight end Rob Gronkowski was one of the most physically imposing players in the NFL.
Standing at 6-foot-6 and weighing 265 pounds, Gronkowski was an incredible receiver and also dominated as a blocker, which made him a unicorn in the league.
Despite the injuries that were always a battle for Gronkowski, he was also one of the toughest players, and his legend grew, even more, earlier this week when the tight end revealed that he continued to play against the Seattle Seahawks in a 2016 game with a herniated disc and a punctured lung that caused him to spit up blood.
