I think the message he's giving you - and one I have in the past - is to not put all of your eggs in that basket. I played in college and when I was your son's age I, my family and coaches thought I'd go farther than that. You never know. But I ended up with two degrees and a very wide skillset. I cannot imagine where I'd be had I kept following that dream, but I doubt it would be the MLB. It's a game primarily and a game exclusively at your son's age. Don't try to plan for the dreams, let whatever happens happen. Give him a lot of options.
