Quarterback Motion

[JimNayzium]

I read a post thread in here abou t the where's the tee casebook usc.

My question concerns this play. Offense tries hard count for fifteen seconds to get defense to jump offisides. then the quarterback walks dejected toward his sideline and calls a timeout.

Later in the same game the offense tries again to jump the defense offsides with a hard count. this time when the quarterback walks slowly away toward his bench, the defense begins to celebrate becasue they did not jump offsides. while this happens the quarterback is the only player in legal backwards motion towards his bench, the offense snaps the ball to the fullback and runs for a first down at the celebrating defense. there are not procedure problems, just a USC question based on the where's the tee rule. the quarterback never verbally says anything or makes a fake timoout motion he just jogs off. what is the call?
