thnx man. WOW. Does this make a difference when giants were on defense?
Well there is a rumor that they had our frequency, but that seems unlikely. It was my understanding that only the Giants were having "radio problems" and switched to their own handhelds. So I don't believe a comm breach was an issue/possible seeing that the Cowboys were still using the league regulated devices (heavily encrypted). Now, if Dallas was having problems, too, and the Giants handed them some ham radios and said "Hey, Friends...use these!", then possible.
But to answer your question. Just having the ability to keep communcation with the QB of your defense up to the snap of the ball (to see last-minute pre-snap movements or giving more time when offense is using hurry-up), compared to cutting it off at 15 seconds prior is an advantage. Do I believe that's what happened? I don't know. More than likely not, but out of spite for John Mara screwing us in that 2010 uncapped salary year debacle, I hope something happens. If the league doesn't set a precedence, then what's to stop other teams from having "comm issues" and breaking out their own hand-helds?
