I think Dan Hampton deserves a spot on this list as he was the most complete defensive lineman in Bears history. It was his presence that created opportunities for Steve McMichael, Richard Dent and William Perry to operate one-on-one against offensive linemen. It was also his presence that kept blockers off of Mike Singletary, Wilber Marshall and Otis Wilson. Having said that, I'm not sure who he would replace on this list. Probably Devin Hester or Dent even though I agree that Hester is the greatest kick returner in NFL history.
