Given that the only time a field goal is made from this distance it is a line drive with low flying trajectory, is it within the rules of the game to put a defender at the cross bar to deflect the ball as it passes.

It seems that this ball cleared by no more than 6-12 inches which for these guys is the equivalent of grabbing the rim of a basket since they are both 10 feet high.

I know you cannot use another players back to hurl yourself over the line of scrimmage but can you block a ball at the point it clears a cross bar and upright.
