"We called plays all week verbally, just standing next to each other. And (in the game), it wasn't the normal headsets they use in games -- it was coming from a walkie-talkie coming into our ear," Lock said. "If you didn't enunciate really sharply, you really couldn't hear anything. A couple times I had to cover my ears, looked over, and they knew to say the play again. You can get 75 percent of the play and miss one part, and you don't want to miss that one part."
