So, Wisky could go anywhere from 8-5, which would be considered decent, to 5-7, which would not. That's a large swing for a first year coach and perceptions.
I believe in at least three years for a new coach, and more than that if year 3 shows some promise and recruiting looks solid.
Billy Napier for example is going to be on the HS if next year doesn't improve and if their recruiting falls off (which it seems to be doing).
