You can go back to the last two Head Coaches of the Black and Gold who made their opponets Black and Blue.
It as you know being a Steelers fan began with Chuck Knoll Playing smash mouth football with Franco Harris ,Frenchie Fuqua
and Rocky Bleier. The defense led by the STEEL CURTAIN would take care of the rest along with the 3 best LB'S in that time
Andy Russel, Jack Ham, and Jack Lambert and our DB'S Mel Blount Mike Wagner Donnie Shell which won 4 SUPERBOWLS
to their credit.
Then the reins were handed over to Bill Cower who had the same miind set control the tempo run the football and let the Defense take care of business. and he was very good at controling the game. In that era we lost LB'S like Chad Brown Greg Lloyd just to name a couple of great ones but Cower seemed to know what to do with the draft and his talent.
In the segment were in right now their passing before we run, and I think the way Coach Tomlin's predecessors feel get the run game established first so you can set up the play action pass to balance out the offense and to keep the defense honest
