There was a kid at our high school who left after soph year because the coach screwed him. He went to a Catholic private and got screwed there. He returned to the high school,and got screwed again. This time my son was a junior. He said the kid grossly overrates his ability. I can say the same thing about the dad.
According to the dad big time programs disocovered his son at showcases. But they ultimately backed off and screwed him. The kid headed for a JuCo first year of college and got screwed. He transferred to another JuCo. Junior year he didn't make the spring roster at a ranked D2. Guess why he didn't make it?
There was some talent there. The kid threw mid 80's. But he was uncoachable. He listened to his dad telling him not to listen to his coaches. Only listen to his private instructors. Picture a high school and college coach being told off by a player he's wrong. I doubt every coach the kid ever had was wrong.
