I guess my point here is that although this blew up because of the Saints(which was awesome and hilarious), it brought a huge problem in the NFL to the forefront. Pass interference penalties are a huge problem in the game and have too much impact. It does need to be addressed and it would go along way for the fans if we held the officials accountable to their mistakes. And after being a Panthers fan my whole life I can confidently recount many many times where one review could have changed the game and or a season.
This kind of rule change levels the playing field for a franchise like us. We have been doormats to the officials and NFL narratives for years. You only have to look at SB 50, or 2014 playoffs vs SF to see for yourself.
People say human error is part of the game but that is just an excuse to see a team get screwed. The officiating should always be progressing. And if it's makes the game a little longer than so be it. If it keeps Cam from being head hunted or Eric Reid being unfairly flagged DPI because a ref doesn't like him then I don't care. I care more about the Panthers winning than an extra 20 minutes.
All they have to do is single out the penalties that are challengeable and or eliminate PI as a spot foul.
