anyone else ever think of maybe having a coin or something that the offense designates either a normal run, or play action run. Then when they line up, he calls run... and the defense adjusts to run... if he had the coin fliped to playaction then it would be a pass, or if he didn't flip it to the other side it would be a normal run. the coin would have to be revealed every run so the guy couldn't make up his mind once he saw the defense. Not sure if it makes sense to anyone, but it could be a way to show run and call run, but the defense would still have to be cautious for the play-action.

and i'm sure everyone is very confused... it sounded better in my head.
