What I found most interesting about the NFLN commercial where Hasslebeck discusses that (besides the fact that they were airing it while people were griping about the Pats stealing signals) is he’s on the offense, he was talking about radioed in signals not visual. It’s really interesting that Holmgren is so paranoid he has a radio play calling method that assumes signal theft, and remember Holmgren has spent almost his entire career in the NFC so anybody that want to turn that on the Pats needs a different dog. I think that’s pretty much proof positive that signal theft is a rampant and inherent part of the game, if radioed offensive signals are assumed unsafe then visual defensive signals (which are legal to steal through certain methods) can’t possibly be safe.
That's interesting. I'd figure they'd use a simple codec/encryptor in the electronics. It's not hard to do, but it is a major pain to crack.
