Wow, I had a feeling someone might ask "what's the difference between Tivo-ing it and making your own??" Well let's see...the cameras of the networks are controlled by the networks. They don't go out of their way to try and catch defense signals, etc. They try to show the play of the game, not steal signals. If you make your own, then surprise, that's against the rules.
And just because there's "so many ways to get around it" makes it a stupid rule? So would you say that the laws against insurance fraud, hacking, etc. are stupid because "there's so many ways to get around it?" It's a rule, get over it.
I'm sure that players are concerned about lip reading. So what? That has nothing to do with videotaping. There's a huge difference between lip reading (being perceptive) and purposely getting a video tape that you can try and interpret later (being deceptive).
As I stated in another thread - it's not the fact that signals are being stolen, it's the method of doing it. If you happen to look over to the sideline and see an opposing coach mouth "BLITZ," that's not against the rules. But using deceptive methods to try and steal the signals, that is.
Well, I'm glad your video guy wasn't smarter than a 3rd grader then. Because somehow, he got caught.
