IMO, if we consider A22 moving forward by going into a 3 point stance and flag that, it's going to be a long night. The rule states only 1 player MAY be in motion, he doesn't have to be moving side to side, as long as he is not moving forward, he is legal. Again, all 11 players have to be set for one second at some point before the snap, but one may be in motion. I'm interpreting that one man in motion can basically move anywhere he wants as long as its not forward. I'm not picking this booger.
