Finances? I wouldn't trust my son at that age to purchase a used car; at that age he thought money sprouted from the ground. At a private school, a 50% scholly still leaves over $140,000 to harvest from the garden; so, only adults can truly have the context to navigate the finances (and each family differs).
Basically all baseball stuff we left to him - facilities, gear, whatever. He decided his variables and the weight each got; he owned the decision.
Academics we spoke; majors for the other players, careers/jobs recent players who didnt go pro work, etc.
Before the process heated up, m, d, and s determined alot so that we could be on the same page. For us, that primarily meant the pond he fished in was decided early.
