I agree with you that other teams have been cheating (Seattle tampering with K-ball).
However, nobody has gone as far at the Patriots have, lets review.
1. Cutting off visting team headsets during critical drives.
2. Using multiple frequencies to jam/intercept coach to QB communication
3. Mic up defensive lineman to record audibles, snap count, ect...
4. Video taping other teams sideline.
Multiple coaches have come out and confirmed this, not just 1 guy making allegations.
NOBODY HAS TAKEN CHEATING LIKE THIS TO THE NEXT LEVEL LIKE THE PATS. THERE REALLY IS NOWAY TO DEFEND THEIR BEHAVIOR.
