Our programs (football and basketball specifically) always run the risk of losing a coach after a relatively short period of success (e.g. Kragthorpe, Graham, Tubby, Self, Manning, etc.). Not sure how anyone can peg the current candidates as more or less likely to bail after one or two good seasons. That's always a circumstantial thing and varies from coach to coach.
Bill Self, for instance, wasn't looking to take another job but then the Illinois gig opened up unexpectedly when Lon Kruger left for the Atlanta Hawks. If Wake Forest doesn't open up last year, Manning is probably still in Tulsa. Steve Kragthorpe might have stayed in Tulsa another year if it hadn't been for his relationship with the Louisville AD.
So to say that Frost would bail after a year or two but Wells or another candidate wouldn't is pure conjecture.
