Right.And the thing is they've had highly rated running backs in the program. Granted, quite a few of them flaked out for various reasons, but it's not like the running back room has been void of talent the last twenty years.
Just the way we go about everything in trying to win football games...
...our focus is so greatly on defense that our offense plays a far second 'fiddle' in overall strategy.
Every game it's "let's let our defense go out there and dominate while hoping we can muster up some touchdowns allowing us to win the game."
Iowa has been winning a good chunk of football games and it's great but, after a lot of (overwhelming majority) those wins it's "man the defense played LIGHTS OUT but why does our offense struggle so bad? We should have steamrolled those guys but whew, at least we won."
Winning is great but I wish we had more of an offensive-minded way of winning is all.
