The Pittsburgh Steelers entered the 2022 regular season carrying seven defensive linemen, which is an extreme rarity for a team running a 3-4 defense. Pittsburgh has in the past only done it under exceptionable circumstances in the past, involving either injury or a prominent contributor on special teams.
They also customarily only dress five of six defensive linemen on the roster; now with seven, they have been dressing six, and it has been second-year Isaiahh Loudermilk who has been the odd man out. But according to Gerry Dulac of the Pittsburgh Post-Gazette, that may not be for much longer.
