I keep hearing media folk saying it's not an advantage...the logistics make it unable to help...well. Most teams have around 60 plays a game. So in the first quarter during NE's plays they tape the defensive signals, so after 1 quarter a 2nd person breaks down the signals to what they did rushing and in coverage. This won't help a lot after 15 plays, but now you tape the 15 plays/signals in the 2nd quarter. So after halftime you have some idea what the signals mean. 15 more plays in the 3rd quarter means that in the most important part of the game, you have a very good idea of what is being called. Even if you just make one play because of it, in today's NFL one play can make the difference between winning and losing.
