With rules favouring the offenses so heavily in the NFL, I believe that the intentional grounding penalty should come with an additional loss of down.
Meaning say it’s 3rd and 10, QB doesn’t get out of pocket, ball doesn’t get to line of drum mags, no receiver etc etc and he throws it away, i think it should be a dead spot foul, but the ball is now turned over to the opposing team. The 4th down should be nullified.
I think the defense should be rewarded for great coverage with additional pressure.
The whole point of intentional grounding is it grants the defense a sack they had earned but for the illegal pass. A sack doesn’t cause the loss of an extra down.
Intentional grounding is essentially the photo negative of defensive pass interference. They both grant the non-offending team the high-value outcome that likely would have happened without the cheating.
