A first down off of a defensive pass interference also allows the probability of an ISU win to go up, but the refs screwed ISU over. All I am suggesting is a run is no sure thing and I don't agree with those who blindly say 2 runs would've won the game. Of course running and punting is the norm in the situation, but that doesn't mean the norm ends up working out 100% of the time.
If Campbell could do it again, he probably would run it, but he can't. This is my point. Regardless of whether everyone in the world wanted ISU to run, they threw and had a successful conversion that was taken away. End of story.
Yeah, ISU did that exact thing against iowa...ran three times and forced them to use all their time outs. That didn't work so well and Manning got raked over the coals for not being aggressive enough. The biggest key to me (other than officiating) is that ISU's pass defense can get torched when teams are forced to pass...even by an average QB like Stanley or a FR like Thompson.
