ISU does not the Oline and skill set at running back and WR to not have Purdy running the ball. Look at OU last year, Murray great passer, but could also take off on the RPO.s, Texas's best runner last year was the QB. Yes, I know he is bigger, but ISU just does not have the offensive talent to allow Purdy not to run.
Hell, I am not sure exactly what type of offense we are trying to run, are we a spread team, a power running team or what? If you want to play power football like KSU, then we need a fullback that can block and the QB has to run the ball. So far through one game, I see none of that, and we didn't the last 3 games last year, Texas, Drake and W. St.
Bottom line, to me, Purdy needs to at least be a threat running the ball off the edge, to slow down the backside DE. To do that, he has to run 5 to 10 times a game.
