Hire Matt Campbell now.
Here is a problem, you are Matt Campbell, fat, dumb and happy at ISU. If you have not been in the process of the PSU coaching search and now, Kraft calls you, it reeks of desperation and not a hire that was made through a courtship.
Campbell seems content at ISU, no doubt his name has been in searches for other programs but it just didn't happen. What do you do if Kraft calls? I guess you hear him out. You will know the program is taking on water and will take time to recover but then you certainly will have a ton of leverage over Kraft.
I think this is the problem now. Kraft now has to go to candidates that he hasn't contacted before and those candidates know the desporations are real.
