There were plenty of bad & missed calls in both championship games. Tony rHomo had made a comment they seemed to be going the Patriots way and then the refs missed two DPI calls in KC's favor.
The Saints are the team with the only really valid gripe, that was the worst two missed calls I think I've ever seen. The defender never even looked for the football, his whole intent and focus was leveling the receiver, and he got away with it.
I really love how the people who beat the cheating/conspiracy drum the loudest can't understand how unlikely it is that so many refs, so many play reviews over so many years all "going the Pats' way" is nigh impossible, and also not borne out by the in-depth review of these "myths". The Pats are like 20th on the list of most roughing the passer calls since the "Brady Rule" was instituted. The Bills, who are the most vocal advocates of claiming preferential calls for Brady, have actually been the most frequent recipients of roughing the passer calls.
Opinions without data always results in a skewed perspective of the truth...
