Who is the toughest player in the NFL?

With an exciting week of football behind us, we as fans got the chance to see the true make up of some teams. The Broncos relentless desire to win, the Steelers toughness, and the Packers dominance, all have been highlighted over the past few weeks, but especially during week 14. The Steelers, to me, seem like a serious contender to make some noise if Big Ben and Pouncey can rebound from their injuries. I say this based on the demeanor of their team. They have a dominant defense that is full of playmakers and ball hawks. Their offense is uncharacteristic of recent Steeler teams as they use mainly the passing game (ranked 9th in the NFL) to score a majority of their points. But the strength of their team is not in their talent, it is in their toughness. Their quarterback has fought some major injuries this season, only to perform better and better each week. Big Ben is not only one of the most underrated quarterbacks in the league, but he is also willing to put himself on the line to get his team the victory. I am willing to say that Big Ben is the toughest player in the NFL. Who do you think is the toughest player in the NFL?
