A different "illegal fwd pass" situation

[Trap]

Ok, hypothetically.

You have an option offense, the qb runs around the end 10 yards past line of scrimmage, is going to get tackled, pitches the ball to the running back, who is now 1 yard ahead of him. Not expecting the ball, doesn't catch it, ball is recovered by defense.

So now you have to tell the coach that it is not a fumble, but an incomplete pass. I'm not arguing the rule, just that it defys logic and penalizes the defense. These are the types of rules, that enforced correctly, make officials look bad.
