I agree with fogelson on this. My highschool track & field coach was very good (though he didn’t spot or didn’t train what I was best at - javelin); my judo coach was a tremendous role model for me (despite not being that good of a coach); my basketball coach wasn’t very good, but he was still a good influence on me too.
You are concerned about the quality of your offspring’s highschool track coaches, before they are even born, before you find out if they want to or are good at track…
