Secondary blitzes were once a pretty notable part of Dick LeBeau’s defense with the Pittsburgh Steelers, particularly at its peak around the time of the team’s most recent Super Bowl appearance. All of the other pieces were in place to make the blitz of a defensive back most effective, and it got results.
For example, in 2009, the Steelers managed to rack up three sacks from the secondary, with William Gay, Ike Taylor, and Tyrone Carter each notching one for themselves. In 2010, Gay had two sacks, as did Bryant McFadden.
