Let me try to simplify it for you. Man, you have to get back to work. Your mind is getting soft and slow 
Say there are 20 bad calls in a game between BYU and GU. Your thinking means that there would be 10 against BYU and 10 against GU. But, there is no logical reason for that. There could be many variances that can cause 15 bad calls agains BYU and 5 bad calls against GU. Does that help?
Thanks for the explanation…
for BIAS!
That is exactly what you described, that was perfect.
That may happen in a particular game, but over the course of the season there is no logic for it not being about equal for everyone. Bad calls have very little to do with one team being better than the other and everything to do with randomness. It is a stretch to think that bad calls only go against the weaker team. I have seen bad calls go against the better team just as much.
That is called logic and reason.
Actually refs do notice one team better at every phase of the game. They call it accordingly. And the length of the season has nothing to do whether it will equal out. Bad officiating.
