Not rigged, and the refs are not in collusion. (shock coming from me right?)
However, I think some refs are a bit biased for and against certain teams / players. Or else, why do some refs call or do not call penalties the same way each time, and for or against certain teams.
Such as, Brady and Rodgers, Big Ben get breathed on, and gets flags. Dak, and Cam Newton, a few others, get killed, but no flag.
The NFL refuses to do anything about it, so therefore, it seems it is rigged, or maybe the better word is "weighted" for certain teams and players.
However, I did notice, later in the season, and in the playoffs. Brady and Rodgers did not seem to get that treatment, if anything what normally would be in their favor, was not. That was good to see.
As for Dallas against SF. Dallas screwed themselves, by playing just awful. Yes a few controversial things, if you could call them that. But if they were disciplined and played better, those would been a non factor as in most calls.
I complain, and mostly in the heat of the moment in game threads. And to get a response for fun. But many bad calls, or non calls seem to happen at weird times to us. That is a fact.
Doesn't matter at this point, can't do anything about it. Not going to waste brain cells on it.
Looking forward to the off-season moves, and improvements, if any.
