Playbooks
23 personnel puts 2 running backs, 3 tight ends, and 0 wide receivers on the field, the heaviest grouping most playbooks carry outside of true goal line packages. It screams run and forces the defense into base or goal line personnel, pulling nickel corners off the field and replacing them with run-stopping linebackers and extra defensive linemen. The tradeoff for the defense is coverage quality: once they sub heavy, any tight end running a seam or flat route is matched against a linebacker or box safety, which is exactly the leverage you want on play action.
