If you haven't already, sit down with your son and draw up the things he wants in a college and baseball program. All things, such as distance from home, student life, athletic facilities, degrees, cost, etc., etc. Then begin to prioritize each of those things in order of importance.
Then begin to map out which colleges best meet those desires. Hopefully, a few of them will be schools that have already been in contact with you. From there, begin to map out a plan for your son to begin initiating (or continuing) contact with those programs. Consider camps that align with those schools attending. Work to get unofficial visits with the schools on his list that show interest in return.
That's where I'd start. You may already have done that. If you haven't, and the plan is to see who reaches out and pick, then you'll likely end up with little leverage and potential buyer's remorse.
In short, get a plan and start executing it. There are a million threads that fill in all the blanks I've left, but your son needs to start driving the recruiting process or else the recruiting process is going to drive you . . . . nuts.
