Football team in Pittsburgh, Pennsylvania, so named because of the abundant [steel industry]? in the city. The team won four Super Bowls and is regarded as The Team of The 70's. Don't let anyone tell you they won four Super Bowls in a row, in fact they were IX, X, XIII, and XIV.
The team had a dominant defense known as The Steel Curtain and an offense led by [Terry Bradshaw]?, [Franco Harris]?, [Lynn Swann]?, and [John Stallworth]?. Their coach was [Chuck Noll]?.
If you know anyone from Pittsburgh or have visited there, you may know that locals don't pronounce the team Steelers with a long e. It sounds more like Stellars. I think that isn't just because of their local accent, but because they think the team is pretty stellar.
