When he's healthy, Rob Gronkowski is probably the best tight end in football. ''When he's healthy'' being the key phrase here -- Gronkowski has had several injuries that caused him to miss key games in his career, and reports of a possible fourth surgery on his left forearm don't seem to bode well for his future robustness. The Patriots are known for their punishing passing attack, but without a healthy Gronk, they're just not the same team.
All three of the Patriots' marquee receiving threats have had injury issues. Danny Amendola missed nearly all of the 2011 season, while Aaron Hernandez has never played the entirety of a 16-game season.
