PROS: Kid can relax and play without the pressure of pleasing. Time can be spent cleaning up/improving their game. Money can be saved, limit travel/tournaments/showcases, go to committed to college's camps. Focus on grades, like baseball they can never be too good. Parents get to post on social media.
CONS: Staff that recruited player leaves, RC that loves your son takes another job and HC has no idea who you are. HC is fired, resigns or takes another job. You stop working because you "made it" and it shows, they decommit from you because you have not progressed. At 15 they recruit you based on how much they expect you to develop. Kid has no idea what he wants to do with his professional (not baseball) life, that school have a curriculum/major that fits?
That's just a start, this should be a fun and informative thread to follow.
