gyroscope made of a football, when thrown in a spiral?

  If it acted just like a gyroscope, wouldn't it remain tip-up when the receiver catches it?

    i'm not sure, but that's a great question. Precession?

      The answer presented in the article (er.. video) is that the drag from the air on the ball's trajectory is the stronger force, and it changes the attitude of the ball.
