Which is the argument that stupid people ALWAYS make when they don't have an actual argument to rebut what is presented: straight to ad hominem. Why are they stupid? Because they're inherently biased, too. Predicating your argument on bias when you have your own is pointless because ultimately all it serves to effect is ad hominem against oneself.
Are you a stupid person? Did you stupidly buy into Spygate last year because of your bias? That's okay. Happens to us all. It's the smart people who will realize that it's time to course correct. It's already become one of the great running jokes of sporting injustice waged as a wag-the-dog affair of political convenience for the league's commissioner, and the rest of the NFL's front office. Nobody look at Ray Rice behind the curtain! Look at how tough we are on Tom Brady and Adrian Peterson!! Hell, Bill Nye owned himself in a scientifically inaccurate diatribe on this very subject (probably for no other reason than because Brady and Belichik were known Trump supporters, and Nye has difficulty with controlling his own political...wait for it....bias).
I don't know why so many NFL fans can't seem to handle the Patriot's undeniable greatness and (legitimate, fair) domination over the league, but for some reason, many can't.
