Sorry, I don't mean to belabor the point, but I'm still confused. What yardage would be added on to the end of the run (or play in general) just the yardage that gives them a first down? or..? Give a scenario please for how a holding play would unfold where there was positive yardage gained. Please
Yeah, no worries and I think I misspoke on the running play only. That part might be accurate (see below). The 5 yards AND an automatic first down piece means you get a first down IF you didn't make it on the play. So if you run 3 yards on 1st and 10 from your 20, you get the 3 yards plus the 5 yard penalty to take you to the 28 and then it's 1st and 10 again (automatic first down). But if you're on the 20 and run 12 yards to the 32 and get a defensive holding, you get the penalty tacked on and moved up to the 37 and it's 1st and 10 again.
RULE 14: PENALTY ENFORCEMENT
SECTION 4 SPOTS OF ENFORCEMENT
ARTICLE 2. FOUL COMMITTED DURING RUNNING PLAY. For a foul committed during a running play when there is not a
subsequent change of possession during the down, the basic spot is the dead ball spot. The three-and-one method of enforcement
is used (see Section 3, Article 6).
Note: A foul during a run prior to a forward pass or kick from behind the line is enforced as a foul during a passing play or
during a scrimmage kick.
So based on this, if you are on the 20 and pass to get you to the 28 yard line, you get the result of the play and stay at the 28 for 2nd and 2 (decline the penalty) or get moved to the 25 and have 1st and 10. If you pass to get you to the 32 yard line, you get the result of the play and can decline the defensive holding and take your 12 yards or take the penalty and get 1st and 10 from the 25 (obviously you decline).
