As a parent, my job is to mentor and guide my son to become all they he can be based on his strengths/weaknesses and long term goals. I feel very passionate about that for my 18 year son as well as my two younger ones.
Based upon everything swampboy has shared with us, I know there are schools out there that will meet his son's needs of baseball first and education second. I agree for some kids the preferred path may be to pursue professional sports while others want to become Drs, lawyers, engineers, etc.... Opportunities to go down a professional sports path is just as slight as an opportunity to pursue a prestiguous university degree. Again, our job as parents is to help guide them and show them the differences when appropriate. Show your son the path where he has the best chance for success, and he can understand the risks & rewards.
