I agree. Normally they don't swing much but over the years I've noticed a bunch of games that swing in 1 teams favor with the refs. Like the Superbowl last year for the Rams. No live ball fouls until 60ish seconds left in the game then the rams get 4 on 3rd or 4th down to extend the drive? Coincidence I'm sure.... I have some more Vikings examples but I'm biased and could definitely be exaggerating in my head. I don't think the NFL sways every game but it's pretty clear they occasionally do.
