THIS!!! Your O-Line probably has it in the back of their head, "Jeez, I don't want to be too far down field in case we do actually pass it" I didn't play in the Big Ten or the NFL and I know running RPO from the two yard line is the dumbest thing I've ever heard.
The first question that Tom Miller asked he deflected, and essentially put it on Jerry. Saying that we called RPO and Jerry made the read based on the amount of guys in the box. Of course they're going to be outnumbered you're on the 2 f'ing yard line. Call three runs in a row and you score a TD.
Just don't understand RPO on extremely short yardage downs, you run the risk of ineligible player down field. Maybe I'm "old school" but I think you line up under center and give the ball to your RB. Maybe if Z was healthy that would've been the play call.
