The Steelers are most famous for their defense. In the 1970s, their defense was nicknamed the "Steel Curtain". It helped the Steelers to four Super Bowl wins. Other well-known Steelers defenses include the 1990s "Blitzburgh" defense and the 2000s defense (which was not nicknamed). The Steelers always have success so they are considered the best NFL team of all time. More recently, they acquired the best player in the NFL and single season sack record holder T.J. Watt. Other notable players on the team include quarterback Kenny Pickett, running back Najee Harris, wide receiver Diontae Johnson, wide receiver George Pickens, interior defensive lineman Cameron Heyward, free safety Minkah Fitzpatrick, and kicker Chris Boswell.
