While I agree with the points presented about the importance and characteristics of a coach with integrity...and their critical role in fit...
Without any attempt to hijack the thread, I'd take a bit of a different view....
While a coach can be a great help...as players mature, at some point the player has to become bigger than the coach...and bigger than the program...while still being an interal and critical part of the "team".
Meaning that at some point a player has to take responsibility for his own destiny rather than leaving it in the hands of the good/bad coach or the level of the program, or anything else.
For those who rise, nothing stops their progress, not even poor coaches. Good coaches are a great tool, bad coaches are a nuisance. Players on the way up learn to adapt, adjust, learn to refuse to use coaches as an easy way out of self responsibility. As a result great players come from and rise from all sorts of programs and situations...it's character, it's maturity...not just coaches with integrity.
