The fans who believe this is a misunderstanding, or a mistake....are playing checkers, and BB is playing three level chess.
It's not about teams...it's about offenses, defenses, and the coordinators that run them. Bill B has been cataloging and updating tendencies of coordinators through illegal filming for decades. He might be filming the Bengals, but it's just more info in the catalog. When he faces a team in the NFL, based on the information he has acquired, he has a much higher percentage of success against teams. I can remember games where the Colts played them that it seemed every single play, they knew exactly what was coming....exactly. Peyton devised a way to change plays at the line and confuse them, and that is why the Colts were pretty successful against them in the later part of the rivalry.
The Patriots are a cheating franchise. They are also very well run, and no one can deny that. However, When the filming evidence was destroyed, it was nail in the coffin proof that their practices....revealed, would have struck a blow to the integrity of the NFL.
