The Pittsburgh Steelers fielded perhaps more players on defense this season than they ever have in their history, and that came about due to a variety of reasons—not simply due to injury or even due to complications with COVID-19 protocols. The secondary in particular caused them to employ a number of different personnel and packages.
They ultimately played 11 different defensive backs, from Joe Haden, Cameron Sutton, Minkah Fitzpatrick, and Terrell Edmunds, to James Pierre, Arthur Maulet, Tre Norwood, and Ahkello Witherspoon, to Miles Killebrew, Justin Layne, and Karl Joseph. Witherspoon was among the latest additions but played the largest role behind the starters.
