There is no way to know until a coach gets here.
I would love to see Lon come back, but he won't.
Huggins has some baggage that would take a lot of schmoozin' to convince both Weiser and Wefald he'd be a good fit (Assuming, he'd want to come here in the first place.)
Majerus would do very well at KSU, but he has health issues.
As far as the others, it's much more up in the air, but again, the issue is fit.
