			Where was A1 when he was contacted by the B player?  If he was occupying the same yardline or further then I'd say you may have something, otherwise if they're facing each other and it's B facing / blocking and throwing A off his route you don't have anything.  The NFL has this 5-yard chuck rule but at the Fed level they can do that all the way down the field up until the A player occupies the same yardline (or beyond) or is moving away from B.
