The superbowl, some questions

[bhaexpress]

I don't think that's true. There are one or two preprescribed moves where the ball is switched from QB to one of the blokes behind the scrimmage who then hands it to the bloke running the opposite direction.

But I think you're right with the basic premise. The ball is generally not passed more than once because of the risk of the ball being dropped. A turn over can be punished heavily. This is why a punt is usually the course of action on the final down if it looks like the yards aren't going to be made.

Actually there can only be one FORWARD pass in a play, the ball can be passed backwards (latteralled they call it) as many times as you like. It isn't done that often but trick plays (called 'Flea Flickers') will do that.
