Peyton Manning

FILE - This Nov. 25, 2012 file photo shows Denver Broncos quarterback Peyton Manning (18) calling a play during an NFL football game against the Kansas City Chiefs in Kansas City, Mo. The best spies in the NFL these days aren't behind enemy lines but on the quarterback's own side of the ball. Every game, two of his interior offensive linemen are miked up for network TV, bringing the sounds of the game to millions of viewers _ and future opponents _ who hear the quarterback's cadence, codes and cues, all of which are enshrouded in an increasing amount of gibberish.\ (AP Photo/Ed Zurga, File)
