There are three levels (my view) of D1. There are the major conferences and other ranked programs. There are the mid majors. Then there are the bottom feeders. If your son fell into major conference/ranked and pro prospect he would likely be committed to a college program already. His travel coach would be telling him about the spro couts asking about him who come to see him play. If he played for the right travel team the coach would have sat down with him fall of soph year to create a business plan to target the right D1’s for exposure. The coach would be preselling/promoting the kid before tournaments.
At this point dad and son need to create that business plan as soon as possible. They need to be realistic about targets. The kid needs to email all of them to find out what events they attend to scout players.
The ultimate goal is to find a quality baseball, educational, and social environment for college. The big picture is to set him up to graduate prepared to take the first steps of his forty year plan.
Be focused and real. Don’t rule anything out. There are late bloomers and late discoveries. It’s why some MLB players came from mid major baseball programs. But EDUCATION FIRST.
Good luck.
