Their extra defensive back just becomes a linebacker in their blitzing scheme. In sub, it becomes the same blitz, but it?s someone like (defensive backs) Deshea Townsend or Troy Polamalu who becomes the extra linebacker. It?s really a linebacker blitz. It?s the same two guys they?d bring in on regular defense, but they?re actually defensive backs because you have receivers in the game.
