I know the steelers did not win a super bowl between Bradshaw and Roethlisberger, but at least they were in the AFC title game 5 times and Cowher was a very good coach in his first 12 years with 7 playoffs win and 4 AFC title games.
How many playoff win have the Bengals since 1990?
Ben and Bradshaw deserve a lot of credit for the success of the steelers, but they were not alone and the steelers have never as bad as the Bengals was in the 1990's when they did not have Ben and Terry.
