The reality is SCM, NBL1 and to an extent Div 1 don't need good youth league programs, if they need a point guard they will go and recruit one!
Youth League is a nice for good juniors to continue playing after VJBL, but it has little results on Big V Wins or Teams, senior players (good ones) that were there when a kid enters youth league are still going to be there when they finish, so the kid unless better after 2 years will have to go somewhere else anyway.
I think youth league has helped lots more kids chase JUCO & NCAA opportunities, it has become an amazing breeding ground for that elite level kid and has given opportunity for senior guys to keep playing senior hoops.
There is a closer connection to VJBL > YL than YL > BIGV
