Everything I need to know I learned in Tecmo-garten

Roger Goodell claims that he knew all along that Belichick was taping defensive signals since 2000, but Billy Boy's explanation was that he thought it was within the rules to steal defensive signals by taping other teams' closed practices and then using that knowledge during games by calling offensive plays which would work against foreseen defenses.

When I was in college, I played a lot of Tecmo Bowl. If you looked your opponent's controller while he called a play, that was pretty cheesy. Know why? Cause if you did it all the time, it made the game no fun. The defense would swarm the offense before it had a chance to breathe and the offense could advance at will on the other side of the snap if it knew a run or pass play would be called.

It's not that much different to my mind in the real world, and at the pro level.
