I have an idea. Why don't teams just let the QB decide the play, tell the team in the huddle, change it through an audible if he doesn't like the defense and then run the play? Or have a coach on the sideline bring the QB over, then whisper the play in his ear?
It's idiotic to call it a violation when teams are choosing to send in plays visually from the sidelines. It's just as stupid in baseball, when the friggin' manager is having to call every pitch from the dugout. If you have the ability to decode the signs, then the other team should figure out a better system.
I know, the fast-paced, hurry up offenses are "progress". Let the offenses hold on every pass play, make every hand-check a PI, prevent the defense from knocking the crap out of receivers coming across the middle, and let the offense only allow defensive substitutions at its discretion, but let's cry like babies if the other team can determine what play we are calling due to us putting McD's arches, a head shot of Tony Romo, the letter Q and a cartoon cat on a poster board to send the play in.
end old fart rant.
