Some of the calls here I don't necessarily disagree with, like the roughing the passer penalties against Mahomes. Also, with a full season to work with, you could persuasively cherry pick evidence of bias helping or hurting any team; unconscious bias is inevitable. Finally, anomalies do happen; getting pocket aced three times in a row doesn't necessarily mean the dealer is cheating.
But I don't see why all this can be true AND that it's also true the refs are deliberately influencing some Chiefs game. In fact, it might be naïve to think otherwise, given the truly enormous amount of money at stake and how easy it would be to pull off.
Bottom line (to me): With normal levels of ref bias, the Chiefs would have won maybe 12 games last year, would not have hosted the AFCC, and would not have gone to the Super Bowl. I'm not claiming there's a league-wide conspiracy, but I'm pretty sure someone has been putting a finger on the scale these past few years to make sure the Chiefs succeed. Why they would want a petulant, mincing whiner like Mahomes to be the poster child for the league is another question.
