With all the camera angles/instant replay, we don't see any bogus officating in todays game. Not saying it hasn't happened once upon a time, not that I've ever seen it happen.
The Steelers one of the more interesting stories in the league. From doormat to being the most successful franchise in league history. Don't forget they were one of the NFL teams sent to the AFC when the leagues merged (Baltimore Colts, Browns the others). Those 70's Steelers teams right there with the 60's Packers, 80's Niners.
One of my fav players was John Henry Johnson a Steeler fullback back in the 60's, the Marshawn Lynch of his day. He was known for his patented forearm shiver.
He did start out a Niner. He was there with two other future Hall of Fame backs, Joe "The Jet" Perry and Hugh "The King" McElhenny. They also had Y.A. tle a future Hall of Fame QB.
