Tuck Rule Game

1) A moment in time when the magic of the Raiders was transferred over to the Patriots.

2) A conspiracy against the Raiders, shortly after 9-11, for the "Patriots".

The Tuck Rule Game came about because George W. Bush wanted Americans to support his regime after 9-11, so he rigged the game in favor of the Patriots. You're welcome Patriots fans.
