I am sure I am in the minority but I'll throw this out there anyway.
I get why people are upset but I also think people forget how bad it used to be before replay. I think what has changed more than anything are more rules and a million times more scrutiny with frame by frame analysis, social media gifs, 24/7 NFL networks, non stop analysis of the bad calls....that is what is more different than the actual performance of the refs which has always been and always will be inconsistent and subjective. To some extent you get some calls you lose others, that has and always will be part of the NFL, NHL and every other sport.
The refs cant see everything in real time, I think most people can understand that,so use technology to get it right if you can.Before replay, there were obvious called scoring plays that today would be reversed, obvious called turnovers that today would be reversed, obvious called catches that today would be reversed, etc. My point is there are aspects of review they are doing well.
Now this stupid idea to carve out pass interference as reviewable for called AND NON-called penalties is just terrible to watch it play out. I really think the refs are just doing "silent protest" of sorts and not reversing any of these. Not sure why they are doing it when some of these are so obvious other than reviewing non called penalties opens up a pandora's box I don't think we really want to open. Today its PI, tomorrow its holding, hands to the face, helmet to helmet contact and other things that might happen on every play but lets just wait for a big play by the opponent and then find a reason to reverse it.
Personally, I would like to see reviews for called penalties to get rid of obvious calls they got wrong but to go to replay to throw a flag is a terrible idea in my opinion.
