NFL Audio Tapes

The story is that the Miami Dolphins bought game tapes of the New England Patriots with audio so they could listen to Tom Brady's cadence and audible calls. Why is this even a story? This is so stupid that it is one of the lead stories on ESPN's Sportscenter. Why aren't all teams doing this in all tapes? This should not be an innovative technique in the year 2006. Maybe it was innovative in 1976. From the sound of it, it is reporters trying to create a story when there is no story. Or worse yet, it's the Patriots complaining about something and giving themselves an excuse why they were shut out on Sunday. It's a non-story.
