Thanks for answering, I was wondering the same thingYou would still do the complete arm circle but they just wouldn't see the release. Therefore, they can only judge the speed of the ball but still have the time to gather. Thus, if they have to sit and wait in their gather on a change up, so be it. The off speed pitches, again so be it. The fastball is straight through. It takes time and repetition but they'll get it eventually. Like I said, they'll hate it but it definitely works.
