My son's pitching coach did an interview once on rehabbing the many TJS players he's had to deal with.
For pitchers, sometimes control is the last thing to comeback, making it more frustrating.
One needs to make sure, if given an opportunity, that it is with a pitching coach that is patient and will be able to assist in getting over the frustration that occurs while waiting for all of your stuff to get back to normal. That may become a very important factor in decideing upon where to play or who sees you play.
Piratefan, your son could commit to a JUCO program and continue to play next summer and still be given an opportunity before fall classes begin at a D1, D2, etc.
