Completely agree. It’s sad that good coaches can’t come and get some time to build a long term program. Now you’re hoping to have 1 big year in 3-4 years and then they’re gone for a variety of reasons !I know you are specifically talking about HS coaches but the list of people who stay at a single job for 15 plus years is declining in every field of life. IF a school can get a good coach for 3-4 years they would take it and then look for another good one. It's the way it works.
