90% of Athletic Directors do not knock on anyone's door for a track and cross country coach. They post the jobs and wait for people to apply! Most AD's do not know anything about our sport, especially at the DII level and below. There are exceptions at the big time schools, but those are few and far between! I was a HS coach for 9 years before getting my first full time college head coaching position. I had a lot of success coaching HS and it was a good transition to go to a smaller NAIA school to help build a new program. There is a lot to learn when you go from HS to college and coaching is a lot more than just showing up to practice at 3;30 p.m. everyday and putting runners through a workout. So someone with more college coaching experience, no matter how many national champions they have coached is more appealing than a HS coach who will have a bigger learning curve at the college level in things other than practice. Budgeting, traveling, compliance, etc. But I would say that there are a lot of very good HS coaches out there that would probably make great college coaches.
