No one is trying to give Manning a ring.
This is a professional sports league so I don't believe there is any conspiracy theories to apply in this case.
As for bad reffing. I don't believe it is bad reffing. After watching games for almost forty years the standard for enforcement of the rules has improved, but no where near what the cameras have been able to deliver to the masses.
If I was offered a job in the NFL the last one I would take is being a ref. If 100% accuracy is the demand of the customer base, the fans, because they have (16) cameras and three cracks at instant replay. Then I would demand as a ref the authority to stop every single play to ensure the call was correct.
I would ref with the purpose of a 100% accurately called game, but I would guarantee a 14 hour contest with 700 commercials as I spent most of my time under the hood making sure accuracy was delivered to the customer.
Clearly this is ludicrous, but my suggestion to you is to be cautious about what you expect and want. You can't ask the refs to just be accurate at the time that makes the most sense to you. Everyday there are tens of millions of fans who have tens of millions of unique opinions on how the game should be called.
This is a recipe for conflicting demands and one that makes reffing demanding and impossible to make everyone happy.
