 Longtime field and equipment manager Jack Hart was instructed to do this by Art Rooney as a test to see how the logo appeared on the gold helmets; however, its popularity led the team to leave it that way permanently.Since then, several college football teams such as Michigan State have followed the Steelers approach at one point or another and had their logo on only one side of the helmet.At the end of the 1962 season, they switched to black helmets for the 1962 Playoff Bowl to make it stand out more, and adopted the black helmets full time from the 1963 season onward.
