Some of it does fall on us coaches. I have moved several times on my own due to my mother's battle with Alzheimer's and my father's heart issues. I know it looks questionable to some, but I would do it again to be the son they deserved. However, I have also been places where the administration changes often. And, when admin changes, everything else does too, unfortunately. It is almost never the kids! They are very similar everywhere you go. Most just want to be coached and loved. Most folks get a one year contract, year after year. Admin, to my knowledge, usually gets more than that. It's just a different world today than it was 20 years ago, plain and simple. I honestly think that there is really no one thing, but multiple possibilities and personal reasons. Most coaches I know, work their tails off for the betterment of the youth and their communities. A simple thank you, would make most of them feel a little more satisfied in their jobs.
Thank you to all of my coaches out there. I know what you do, and how hard you work. It does not go unnoticed.
