come on, would anyone really feel the need to cheat against the Lions? I mean the Lions? Maybe a professional team but not the Lions.
Ouch, but so true.
Then why the Jets? Or the Packers?
The thing with cheaters is that they get hooked on it. The success of the cheat messes with their minds. Thinking you have a "secret edge" is powerful mojo, and over time, it erodes and supplants not just confidence in one's own ability to go it alone, but the original ability itself.
That Bellichik felt the need to cheat against the Jets says he's long since past the point where he knew for certain the line where talent and skill left off and his secret weapon began. IMHO, he's been doing this a long time.
