BaseballCoach2,
Ok, so you've been given some great advice about the importance of academics and academic fit with college baseball. We've only scratched that surface, as that can be a whole separate long discussion by itself. Your sons take away should be took look at physical therapy (or similar majors) schools in the context of baseball. You can get a listing of majors by school, location and other dynamics here: http://nces.ed.gov/collegenavigator/
The good news is your son shouldn't have academic eligibility issues with the NCAA. it may be possible that he could be eligible for academic money based on the schools he's looking at, but he has to keep those grades up and understand how academic money is awarded by each institution.
As far as college baseball goes, pretty much every current college player is a former all district player or all conference player. Pick a college and a player bio. Yep, those guys were studs in high school. If your son wants to play in college, that is the level of separation he'll need with his peers. About 6% of high school players go on to play in college (all levels). That is a pretty small crowd. So, it would be a great idea to get an impartial, qualified person to evaluate your son's skills to give you a baseline and a reality check. Check in with his high school coach, travel coach, Legion coach, or personal coach about who is the best person to evaluate him. Local scouts may be in your area and they can provide some guidance on his baseball tools as well.
It is very important to educate yourself and your son on the college recruiting timeline. There is a reason there is an old saying about timing....it is everything. It is so true in college baseball recruiting as well. There is a recruiting timeline because there is a talent hierarchy. Top talent typically goes to top programs early. There are exceptions, but there is a flow to when talent is offered and commits to the D1 Power Conferences and then makes its way to D1 Mid-Majors and eventually D2, D3, JUCO and NAIA. This is the orginal HSBBWeb timeline which is still a great reference. http://www.hsbaseballweb.com/recruit_timeline.htm As you research this more and more you will get a sense of when talent gets recruited to which schools.
So, choosing the right venue for the right exposure becomes easier when you know what you are looking for. Travel teams, showcases, camps are used as a marketplace to bring college coaches and players together to determine if there is interest. Picking where to spend your time and money becomes a personal decision. If you stick around HSBBWeb long enough, you'll get a sense of the activity level required. I'll share my experience with you to show you what not to do. My son wanted to go to school in Virginia...under no circumstances was he willing to go to school outside of Virginia. Well, when he figured out none of the big D1 Virginia programs were seriously interested in him he expanded his search outside of Virginia. Some Virginia D1 mid-majors became interested but they didn't have engineering. So we expanded our search to the East coast looking for D1 level baseball and engineering. While this was going on, a bunch of D3 engineering schools also became interested, so he considered them. What it amounted to was if he had started with his major (engineering) we could have saved ourselves a lot of time and trouble. When it came down to it, he didn't care if it was D1, D3 or D12 (I made that up) as long as they had his major and he could play college baseball. So, please learn from our experiences.
Good luck, and keep the questions coming!
