I agree with TitanBrian's rule change. But I can see your point in not permitting it. I think they're should be some regulation. If a user is using a defensive back to jump the snap I can agree with it not being allowed. But I feel like players like myself are at a disadvantage, because we like to roam and essentially play centerfield with a safety. I like to set myself up pre-snap to be in a good position to jump a route and/or make a tackle. If I know a guy throws a slant I can set that up or if I know he's going to deep I can manually back up. Same thing if I know he's running left I can manually move over without shading my defense and tipping off to the component I know where the play is going. If games are streamed and you can see the guy jumping the snap then yes that is a problem and that should be considered breaking the rules. Just as long as the play is saved via highlights or witnessed during live streaming than proper consequences should be given to that user.
