I think the overall premise of this thread makes sense.
I think after this year and, maybe moreso last year, his stock at the types of schools that would be an upgrade from here has definitely fallen. They might look at a year like this year and go "well, theyre iowa state, they have to rebuild every so often, he just needs more consistent talent like we'd have", but last year might be more damaging to his upward stock in that they go "when he did have the talent, they only went 7-6"
Does that mean we should fire him at the end of the season? Absolutely not. Anyone who says so needs to get their head examined. But I'd guess this will be a much quieter season for schools calling up Campbell.
