The next promotion in Mike's career after Napier left was to be a real coordinator at a fbs program. No other fbs program would have him considered him as a head coach at that stage. The most important aspect to being a head coach is the staff you can bring to a job. The hiring of the defensive coordinator was a sign that he had a limited network of coaches to draw upon. There are only 130 fbs head coaching jobs in the country, much fewer ones where the team has been in the top 25 the past 2 years. The hiring of Mike(no fault of his to accept the job) was an incredibly lazy hire by the administration.
