I was listening to an interesting debate about the PI rule. The debate was that the current spot-of-the-foul rule gives refs too much power in either deciding the outcomes or changing the momentum of games, especially on a call that has a certain degree of subjectivity/discretion to it. The debate was whether the NFL should make it a 10 or 15 yard penalty like it is in college. I know there are decent arguments on both sides of it, but I found myself slightly leaning toward changing the rule to a yardage penalty from the previous line of scrimmage, rather than a spot-of-the-foul penalty.
