Mangina and the Jets filmed the Pats sideline last year but the Patriots didnt care. They only reported it this year because Mangina threw them under the bus
Coach Jimmy Johnson formerly of the Dallas COWBOYS said he used to do it and he knows of others who did the same thing. John Madden used to rifle through the opponents garbage after the games to see if he could find any notes that would give him an edge
Seattle was cheating and they still might be for all we know. They were piping the fan noise into the stadium speakers when opposing teams were on offense so they couldn't hear their signals. It definitely gave them an unfair advantage for home games.
Ever wonder why out of all of the indoor stadiums theirs was so much louder? Their fans don't yell any louder than those in Minnesota, or St. Louis, or Indy. You get the idea. The Colts have also done this as well.
Denver violating the salary cap hmmm thats kind of cheating to.
I mean come one all teams cheat in some way or another.
