Well, luckily for you I think it's probably safe to say we'll find out his ability in that role either here or somewhere else in the future. As for me, I'd rather keep someone with his background and recruiting chops around if at all possible.Nothing. They like Scheelhaase and hate Manning, so their conclusion is that Scheelhaase should replace Manning every time someone goes wrong, even though no one on CF has any idea if Scheelhaase would actually make a good O.C. or not.
As an aside, I don't blame Manning for anything outside of his control. Sometimes players make mistakes, sometimes execution isn't there. There can't be many coaches more committed to running the ball on every first down regardless of effectiveness or the look the defense gives in the country, though. Heaven forbid the team finds itself without a future NFL lead back to make it passable. I did a deep dive on this last off-season, and on early downs ISU runs the ball an exceptional percentage of the time even though they routinely have far more success when they're aggressive and look to throw early and often.
I'll just let it go here though as I know it won't go anywhere. Let's just be glad Scheelhaase is here for the time being.
