For those of you who do not know who he was you missed something special. He was the DC of the original Steel curtain Defense and the assistant Head Coach. He also designed the Stunt 4-3 defense that helped Joe Greene and the Steel Curtain dominate in the 70's.

He was 85 years old. RIP George and thank you for all you did in your time as a Steeler.
