Cowboys Working Out Defensive Audio Kinks

Cowboys play their preseason opener tomorrow night in San Diego. The first game will allow the Cowboys to work a few kinks out of a new audio system.

For the first time, the NFL is allowing one player on defense to wear a transmitter in their helmet to receive play calls. That player for the Cowboys is linebacker Bradie James.

Testing the system out at training camp, it has taken some time for Bradie to get used to the new voices in his head.

"I have to step out of the huddle because there is a lot of chatter," James said. "A lot of guys are talking about what happened the play before. So, now I have to step out of the huddle just so I can hear what  (Brian) Stewart's saying.."

"There's a lot of kinks in it right now,"  Cowboys defensive coordinator Brian Stewart said. "Me getting used to pushing the button for a while and then speaking and letting it go. Then (Bradie) making sure he's got the huddle quiet enough where he can hear or step away. So there's some little idiosyncrasies we've got to clean up."

"I don't want to be the guy to make the mistake, because if I make the mistake he's not going to call the play first, he's going to say, 'Brady what are you doing out there?' " James laughed.
