I think they wanted everyone to flood to ball carrier and leave receiver open. If you have a QB wide, they know he might pass.After watching this, I stand corrected. There was a second option late. The H-back has to block so that JRP can pass, but then slips into a route. Not that there was anytime for him to get open.
Why not have Timmy as the passer? If Gus wants to run trick plays, just put JRP and Timmy in every play so that teams have no idea who the QB will be pre snap. Have them shifting constantly. At least you wouldn’t have to rely on a RB to pas the ball.
