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.
spot of the foul and losing the down is penalty enough imo, basically like taking a sack at the spot of the throw
