Whether the rule is a good one or not is not the question. It's a matter of being able to ever play a team again and say "We played fair" and expect to be believed. They have a definition of what the rule is (whether it is an arbitrary definition or not, that's what it is), something about our cameraman being on the Jets sidelines or something? Clear enough that Bellichick knew it, and broke it.
Once upon a time, when I was down in Baltimore, I crossed paths with someone in a bar and Boston was brought up. "Celtics," he said, "Greatest basketball dynasty of all time."
I was on a plane once, in New York, during a Red Sox / Yankees series. Guy sitting in the same row as me, a New Yorker, told me, "You know, I think there should be a rule that whenever that guy you've got, Pedro Martinez, whenever he's pitching, the other team should just be able to say you know what, you win. We're taking the night off."
As of right now, when people speak of the Patriots, it will be to say "Aren't they the ones that got caught cheating?"
That's what pissed me off. Bellichick is bringing us wins, absolutely, but as of right now he also brought an insane amount of bad press. We're not even getting into the whole sleeping with another man's wife thing, either. I'd prefer to have a football team I'm proud to watch on a Sunday night, and be able to go into work on Monday saying "Good game", rather than justify that "No, I don't think they cheated this time, but I honestly can't say."
