My son played for the butthead in high school. It turned out he wasn’t a bad guy. I had a long conversation with him at a local showcase. But he lacked social and communication skills in general. He was more comfortable bossing kids around than dealing with adults. My son was afraid of him soph season even though he had a great year. Junior year as my son took his place at the top of the pecking order he laughed the coach off away from the field.
I didn’t need coaches and teachers to be role models. We (parents) taught our kids what was right or wrong. It’s a plus to have outside role models. But it wasn’t needed.
