AcademicsFirst,
You're getting a lot of good advice here. A good reality check. Your son is not "projectible". He's a grinder.
You seem to be doing all the right things to give your son the best chance to figure out where he belongs. Your son's academics will open doors for him.
For the "grinders", at some point it becomes a matter of how hard he is willing to work. Web is a "grinder". He surpassed more physically gifted players because he was willing to out work them.
Don't give up on college baseball. His road is just going to be tougher than the more gifted players.
