because it's the genesis of the confusion and the question? obviously he saw the application and that's what sparked the question / discussion.
also for what it's worth, I didn't see any additional information re: running play holding. maybe
@MarcusRock can clarify.
ARTICLE 6. DEFENSIVE HOLDING
It is a foul for defensive holding if:
- a defensive player tackles or holds any opponent other than a runner, except as permitted in Article 5.
Note: Any offensive player who pretends to possess the ball, and/or one to whom a teammate pretends to give the ball, may be tackled until he crosses the line of scrimmage between the tackles of a normal tight offensive line.
- during a punt, field goal attempt, or Try-kick attempt, B1 grabs and pulls an offensive player out of the way, allowing B2 to shoot the gap (pull-and-shoot) in an attempt to block an apparent kick, except if B1 is advancing toward the kicker.
Penalty: For defensive holding: Loss of five yards and an automatic first down.
