As a parent, I think:
//On one hand, it's easy to say "Baseball is the toy department. Unless you're Gerrit Cole or Mookie Betts, there's a time to stop playing games and get on the path towards reality."
But, on the other hand, for those who made it to college as a player, it's basically a lifetime of effort and sacrifice coming to a halt. And, that's a loss.//
But, in a lot of cases, where it's the player's decision, I think they're OK with it, or, handling it better than expected sometimes. In some cases, it might be a relief to get all that off their plate and free themselves up to living life.
