 In 1979, the team gave the Big Ten's Iowa Hawkeyes permission to use the Steelers uniform designs, since both teams had the same color scheme.Aside from Iowa using its Tigerhawk logo as well as continuing to use the block numbers that the Steelers themselves replaced with the rounder numbers in 1997, the two uniform sets remain identical today.The Steelers are one of a dwindling number of NFL franchises that strictly wears its team color jerseys at home, always opting for black.
