Cameron Heyward was drafted by the Pittsburgh Steelers with the 31st pick in the 2011 NFL Draft and played 4 seasons in Dick LeBeau’s defense. His last season with Dick LeBeau Heyward led the Steelers in sacks. In 2015 LeBeau was out, Keith Butler was in and the Steelers drafted Bud Dupree. Since that 2015 season, when the scheme was changed to let the defensive lineman attack more and 2-gap significantly less, the Steelers are #1 in the NFL in sacks, the only team to average 3+ sacks a game for the last 6 seasons.
