Are The Ref's Rigging Games

[Fishingfool]

I have always laughed at people saying that but man some of the calls or non calls are adding up. You had KC's game last week where the KC player pretty much tackled the receiver in the end zone with no flag called. Then you had the Dallas player last night face mask the Giants player and they called it on the Giants player. Then there was the holding flag picked up giving Dallas a TD. Those two calls would have been a 14 point flip in the game. So what do you guys think? Are the refs favoring teams with some of these calls?
