This is currently just an allegation, but it is a bombshell if true and could mean even more punishment for the New Orleans Saints. ESPN is reporting that Saints GM Mickey Loomis had a setup from 2002-2004 where he was patched in to the sideline communications of opponents. Loomis' predecessor, Randy Mueller, used the setup to listen to the Saints' own communications, and Loomis switched it so it eavesdropped on opponents. The setup was taken down when the Superdome was damaged during the 2005 hurricane. The Saints are denying the charge.
