Apparently, Belichick has been taping opponents since 2000! I guess in the last few years he has figured out how to apply the signals to the films to the game plans effectively. There have been coaches who had all the opponents signals in the past, but were not able to effectively use them during a game. I think Belichick needs to banned from the NFL, ala Pete Rose and MLB. Cheating is just like gambling when it comes to pro sports.
