Coach I had a parent that requested a meeting with me because her son was not brought up to varsity for the playoff's his soph year. Her opening line was "You got another soph pitching for you that can't pitch nearly as well as my son." The kid she was talking about was a 3rd rd pick and is in the starting rotation for the Rangers now. Her son quit his Jr year because I wouldn't let him miss during the Easter break to go on a trip with his girl friend and her parents. The mom still tells people I ruined his baseball career and stole his love of the game.
There sure are a lot of threads about bad coaches on this site. And yes there are some bad coaches. But no coach can stop a player who is determined and talented enough to reach his goals in the game. But excuses will do the trick every time.
