*yawn*
Belichick had already reported to Goodell that he had been taping signals since 2000, but that the tapes had never been used for the game. They had been used to compile a library of signals to be used in future games. Most teams change their signals, so the value of these efforts are in doubt. These actions are typical of Bill Belichick's throroughness as far as preparing for games. We don't know how much help they proved to be. Anyway, the first round draft choice was docked and the fine levied when BB admitted such taping since 2000.
Walsh has nothing new to add.
