I really don't buy in to all the conspiracy theories. If I believed that I'd stop watching. I do agree some teams and players seem to get better calls. Not more calls necessarily, just better ones, the calls that matter.
But that doesn't make it a conspiracy to promote certain teams or players, in my opinion. It's no different to me than Jordan getting all the calls that mattered, and I loved watching that dude play from his rookie year until his retirement. They could call a foul against LeBron just about every single play, just like they could call offensive holding almost every play. Just like they could call PP for his sticky hands just about every play--that dude puts his hands on everyone.
It's human nature. These refs aren't immune to the press and highlights and hype.
This happens every single day at work, with normal dudes and dudettes, just doing the best they can--the highest performers, the ones who have a track record, they get the benefit of the doubt, basically 100% of the time.
There's no conspiracy, it's simply playing the percentages in their mind.
We live in a society now where everyone looks for an excuse, the easy way out, someone to blame other than where it belongs.
That forward progress call against us was crap and we all know it. But that didn't lose us that game, and getting that call doesn't mean we win it either. We probably kick the field goal like we had all day, and they get the ball back, so no one can say it cost the game. The Seattle call was bad, but what's worse is Megatron getting the ball knocked out by Optimus Prime on the goal line. That's a play that will lose you a game 99% of the time.
You have to build a winner to get these calls, that's really how simple it is, nothing more. Everyone loves a winner, and we all love the underdogs and the little guys who get hosed. The NFL is in a win-win, every single time.
