I'd like to see JDL a requirement of every club in the NPL/NL1 with sufficient players going through it to populate the under 13 squad in the PYL. If that means two JDL teams per club, then so be it. If clubs want to come up from ZPL, then that is the criteria they have to meet. In that way, the top two tier clubs regenerate from (mainly) within. Limit JDL to premier clubs only so community clubs still get a good number of kids.
Additionally, the top two tier clubs should also be required to have pre JDL structures (u6 etc). There are community clubs that generate these age groups then lose kids to the premier clubs as soon as JDL begins, and it breeds resentment that the premier clubs aren't doing their bit.
I'd like to see PYL squads limited to 14 players. If you are short, play younger kids up. Maximise game time and help spread the talent.
Lastly, I'd like to see regulation that prohibits PYL clubs from getting rid of substantial numbers of kids from an underperforming team, but I don't know how it would be enforced. If you thought the kid was good enough, develop him. Too many times over the last few years there have been clubs that dumped half a squad or more because the team was unsuccessful. Some kids develop faster/earlier than others. Do the hard work. It is a development league.
