The concern is the parents in coaching positions who never gained the hockey knowledge first hand, they are there to pave the way for their kids careers, to control the situation and manipulate other parents into thinking the construct is for the greater good. If your a former D-1 or Major Junior hockey player, spent a lifetime learning the game, played under professional coaches, were taught the game at an academic level, made sacrifices to reach those levels I’d say your more than qualified to coach regardless of your status as a parent, but only playing, playing through 16u or even HS does not give one the tools or the reference point to be a competent youth hockey coach. You can’t paint all coaches who are parents with the same brush, and not all hockey people are great coaches but too many parents are fooled by snake oil salesmen routines and disingenuous recruiting pitches and fall victim to well disguised daddy ball frauds
