And there were a lot of terrible offenses in the 1970s for them to hate...
Not in the AFC Central there weren't. Those were some violent football games on bof sides of the ball.
When you are a member of the Steel Curtain you can pretty much say whatever the F you want.
The Bengals, Browns, and Oilers each suffered some down years during that time, especially on offense, but point taken.
People forget, when they compare dynasties, that the Steelers rose to the top in an era of great teams. Not only did they compete with the Cowboys, Dolphins, Raiders, and Vikings for the top in the playoffs, but the Central was brutal at times.
I think the 1975 team went 12-2, winning the division when the Bengals and Oilers both went 11-3 or something close to that.
