Under Noll, the Steelers went from zero to hero.
The Steelers were in a bad spot before Noll came along and turned them into the “Steel Curtain.”
Of course, in addition to winning IX, X, XIII and XIV, Noll also oversaw nine players who went on to join the Hall of Fame, and coached for 23 seasons in total.
He was recognized for giving African-American players more opportunities than other coaches of his era.
