I'm a Giants fan so I obviously have nothing to hate on the Pats for*. I don't really think this one isolated incident is significant. However, when you step back and look at the last decade or so, there is a clear kind of skeevy Pats culture of bending rules to get any tiny advantage, sometimes to the point of breaking said rules. I don't think anyone besides Pats fans really likes that.
* It's interesting though, that despite getting their four asterisks over the last decade, Boston Pats fans STILL make noises of disgust when I say I'm a Giants fan. They just can not get over it. It's hilarious that some of the most hateful, spiteful, fans simultaneously and pretentiously claim that the whole sports world hates on them because all "they" do is win. Success breeds jealousy, etc. Maybe they should consider the phrase "The world is your mirror."
