I wrote an article profiling Dermontti Dawson for his long-overdue hall of fame induction, and in it I spoke about how he was a bridge from Mike Webster, the old school center, to a new breed of lineman. Strong, agile, and quick. The Steelers are undoubtedly the team with the best track record at center.
