Chris Johnson is a former first round NFL draft pick, and All Pro running back primarily for the Tennessee Titans, and in a recent appearance on the "33rd Team.com," talks about the 5 toughest guys he ever played against. As he puts it, "in no particular order," he names Steeler great Troy Polamalu, Baltimore's Ray Lewis and Ed Reed, the Colts' Dwight Freeney, and the Bears' Lance Briggs. Talking abut Troy, Johnson says when they did scouting reports for him, they never had a position written in, because Troy played everywhere on the field. "You didn't know if he's covering or blitzing. You didn't know what to do against him."
