Gridiron is gridiron. While I won't watch the Super Bowl, it doesn't bother me that a couple of guys I don't even recognize wanted to go and watch a soccer game.
I think it was callled the "Steel Curtain" wasn't it ? "Mean" Joe Green, L.C. Greenwood, Steve Harris, Lynn Swann, Terry Bradshaw...yep. old enough to remember them like you Trotter
The "Steel Curtain" was the nickname given to the front four of the famous defensive line of the American football team Pittsburgh Steelers during their 1970s dynasty years.
The "Iron Curtain" was the symbolic, ideological, and physical boundary dividing Europe into two separate areas from the end of World War II in 1945 until the end of the Cold War in 1991.
