I wonder if Campbell sits and waits. Ryan Day is a couple losses away from being gone. I think someone mentioned his two outs in his contract are Notre Dame and tOSU? But he would be absolutely nuts not to take the Penn State gig if approached.
Then again, would you want to step into a pressure cooker job like tOSU or ND? He could probably lose the rest of his games in Ames and still get a pretty lengthy grace period. Penn State would likely give him a bit of grace too with the potential fallout of transfers and etc.
