 You know, originally it came out as kind of a pick-and-rub style of offense where, you know, there was basically one receiver that was going to catch the ball and the other guys would work to get him free, much like you would in a basketball game, you know, where you're going to pick and try to get a guy open to take a layup or a jump shot. That's what the West Coast offense was originally how it was run. And Bill certainly used that, you know, to his last days as a coach, but it continued to evolve to the quick, short passing game.
