While I believe the NO play was PI, I believe the outrage over that one play is overdone. On close examination, one can see the ball was hot, wide and already up on the receiver at contact. It would have been a very difficult catch. The ref may have passed on the flag thinking it was uncatchable, not the right call but understandable in the real time moment.
The call that should have drawn equal outrage was overriding the Edelman muffed punt call given the benefit of replay. If the criteria is "what most likely happened" then overturning the fumble would be correct. But that's not the criteria, is it? There needs to be clear evidence the ball did not touch him in order to overturn and that was not the case.
I don't have any dog in these hunts. If anything, I was mildly pulling for a NE-NO matchup.
The first thing the NFL needs to do, before implementing replay on PI calls as being mumbled about in the aftermath, is improving officiating quality control. There isn't much consistency from crew to crew. Some are flag happy, others "let them play", and generally there's more "let them play" as the season wears on then into the playoffs. Refs are out there rolling their own. The NFL has failed to address this for as long as I can remember.
My favorite pet peeve has been the PI call since long before this NO incident. There is little consistency in how the rule is applied. The NFL needs to do what they evidently did not do with the new roughing rules, putting together dozens of examples of OK/not OK clips, not 3 examples after the fact, then train the refs while making those tapes public to train the media and the fans. And it does not help that the NFL laid out those 3 roughing examples and then the refs promptly ignored them, nearly ignoring the new rule as the season wore on. Was that some kind of NFL double-secret instruction? And it further doesn't help that the NFL comes up with rules with the foresight of a mole.
The "roll your own" officiating culture is going to be hard to change. In light of that fact, on-the-job training may be required, in which case review of PI calls is in order. I'd make that a coaches call and give him a 3rd. challenge.
