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.
