Realisitcally there is no limit to what can happen....each year/day. Sometimes what initally looks like a bad result turns out great and vice versa, however its up to each player to make the most of his or her journey/struggle. You have to believe he'll learn something for life that will helpful. and not dwell on the negatives or what could have been. You should go where you will play or move on with life with no regrets. its pretty much guranteed to not happen how you think it wll.
Son's D1 coach didn't believe in him, probley would have cut him year 1 except he caught bullpens. Coach didn't get him on a summer team, had to have a scout help him find a summer team. Very disappointing and concerning Coach then told him his junior year he would be a backup, Did he double down to show the coach he was wrong?
No, he left for a JC. It worked out pretty good. Just the same he is still good friends with players from his intial school, not a complete loss! Goes fishing with the scout who found him a summer team. You still need to socialize a bit, it can't be 100% work, there is more to the school experience.
It really is like a job. Find a place you like to work.
