In 1971, a Pittsburgh high school student named Gregory Kronz won a contest sponsored by a local radio station to give Pittsburgh’s intimidating defensive line a nickname. Gregory’s clever play on the Cold War term “Iron Curtain” has endured for over 50 years, and has come to represent fierce Black & Gold defensive football.
