Do you have to think about incomplete "shovel" passes?

[TXMike]

A "shovel pass" is a designed play. There is litlle mental processing that has to go on there. But what you have described is a QB in trouble and passing. There is a huge possibility of there being a foul on the play plus there is a need to be clear that it was the passer's deliberate act that caused the ball to come loose and not the act of the defender jarring it loose. That can understandably take a bit more processing time. I hope you are not so set on showing how quickly you can rule on this that you are automatically tooting your whistle without going through the processing.
