An interesting topic. Just dropped off our son 2 weeks ago to college. A hard transition for him, he's in the school's honors college which is more work, and hopes to try out as a walk on, but like everywhere else, the competition at this d3 is stiff.
Team chemistry can change year to year, but is also influenced by coaching staff. Son came from a nonathletic family (no team sports background, so totally ignorant of the culture, importance of summer travel teams, recruiting process,etc.) so with no summer travel ball experience he was behind the 8-ball from the beginning. freshman year in high school was first time he ever played on school team (grade school too small to field a team), had a blast, came along quickly. Soph year, had a minor injury and was benched the remainder of the year for holding himself out of a game (at my request, big mistake). As a result, he was left behind on JV junior year which nearly axed his chances for senior year. At this point, chemistry and positions largely set on V team. He worked to get on summer team with no luck we missed deadlines, rosters are also largely set in stone by this age) so did private coaching, etc.
School coach told him he wasn't really good enough to play V. So son went through the winter batting program again, came out top hitter in his group (2 groups, they shut him out of the V group, told him no room for him there). Even with this, coach said he'd likely not play. Through the practice leading up to season, there were a few incidents where he was targeted for ridicule/belittling by other players on the team (the dominant ones), and after one instance of lip service to "respect", the coach's treatment of son did nothing but make him an easy target for more of same. He was not supported by any of the dominant players except one, which made the season miserable for him. He received no coaching from staff, was delegating to shagging balls for the other players at practice, etc. He stuck it out, I don't know how, rather than allow the coach to say he'd quit. Son was even shot down in front of entire team for simply saying to coach he hoped he'd get a chance to play that game. Why? Other players stronger, but many more years playing time behind them. Son had excellent momentum, but not the support of his coach. And so, neither did he enjoy any support from his team mates.
This past summer, he did land a spot on a 22U team, one of the best in the region (they had no 18U team to offer). He played on this, had the support of his team mates, got playing time and can always improve, but his coach confirmed to him he has certainly has potential for college playing.
I may not know for many years why son had to go thru the bad experience in high school,with the sport he loves so much, but his personal courage in facing what he did, and his tenacity kept him there. Nothing we could do about the coach, I just wish he'd had the support of his team mates. He was about the only one on the roster taking AP classes, and as such wasn't in the same classes as the rest of the players, didn't spend time with them as a result, and doubtless this had something to do with it - the coach scheduled 4 games for the week of AP exams end of year, including a double header the night before 2 tests. He found fault with son for skipping the games to study for the exams.
Son started going to the college team practices, to get ready for tryouts, so we'll see where it all goes. There have been several life lessons learned through this sport, just wish they'd had a happier outcome for son. Sorry for the long post - it's been a long journey to here. Not intended to be a rant, but yes - team mate support means everything in baseball. I'm thankful son's always been a supportive team mate, hopefully we raised him right.
