A day ago, i would have rated this "WINNER" but after reading the PDF on YourTeamCheats, specifically this part:
Article 9.1 (C) (14) of the Constitution and Bylaws of the NFL (p 39 of this pdf): No member shall: "Use at any time, from the start to the finish of any game in which a club is a participant, any communications or information gathering equipment, other than Polaroid-type cameras or field telephones, including without limitation videotape machines, telephone tapping or bugging devices, or any other form of electronic devices that might aid a team during the playing of a game.” (Emphasis mine.)
That seems to say you can't tape, bug, etc.
I'm just not so sure. It's all so damned ambiguous and out of date (how could you begin to prevent it now with cell phone vids so much better than the 1970 taping equipment?) that it seems impossible to win an argument either way.
The Anderson 2006 memo specifically says signals or otherwise, and that can be taken to mean "You can't tape signals from anywhere, but you can't tape anything from the sideline or anywhere else where the coach can get the info during the game."
At some point, BB will speak on this at length. I hope so, at least.
