What has worked? The pass rush. The Steelers had one of the league’s best defenses in 2019, even as they shuffled through quarterbacks while veteran Ben Roethlisberger was sidelined with a serious elbow injury. In 2020, they’ve taken it to another level. Pittsburgh blitzes more often than any unit in the NFL, on 51.2% of opposing dropbacks, and leads the league by a wide margin in pressure rate, disrupting the quarterback on 46.5% of dropbacks. Bookend edge rushers T.J. Watt and Bud Dupree, who have a combined six sacks in three games, lead the way for a well-rounded unit.
