Problem with NRL, the toss pots who ran the game in the late 90's up to mid 00's, thought we were like America.
Except America has a massive collegiate system for its basketball, NFL and massive minor leagues for the baseball.
They draft these players in to their comps, or buy them in.
The NRL, and for many years before, ignored Country RL and schoolboy RL. You reap what you sow. The NRL want the talent coming through but don't really want to invest in the grassroots, and couldn't because of the conflicts of interest Gallop has as NRL leader and News Ltd lackey.
The U20's came in after Reserve Grade has faded and teams had shared reserves - a la Souths/Norths, Easts/Newtown, Canberra/Souths Logan (of all friggin' places!). Even then, most astute RL people think it's too young. I remember when Dogs fans where howling to the moon that Barba should be playing back in 2008. But the kid was too young. And it was proven. He's still green now, but it's ok because he's a STAR!!! Yes...he is a good player, but freakish talent doesn't get you everywhere without a sound knowledge and grounding of the basics.
Which is where the U20's fail IMO. Too much flair and being told their good but when the grind comes, so many fail. And then they hit 20 and there's no in-between U20's and First Grade (hence Reserve Grade is needed to groom these players so they can learn and go up and down from 2nds to 1sts for experience).
Plus, you're seeing every Islander kid under the sun filling these sides. But one of the telling issues here is many of them don't have birth certificates. So they're hulks at 14/15 but they're really 16/17. So these hulking kids smash the smaller, younger kids out of the game...cause let's face it, which kid wants to get smashed to pieces by a hulk (and which parents want to see their sons rolled by the Titanic). And when the other kids who do hang around naturally catch up in size, it's not so easy any more, and a proportion of the Islander kids shift away from the game also.
Now the ARLC has their billion dollar booty, hopefully proper grassroots footy is attended to and it's not splashed in to Cam Smith or Jonathon Thurston's pockets. I'd like to see proper school kid footy, proper junior pathways in all states, proper training etc and a proper reserve grade, with overhauls in the country/state cup leagues as well as social footy where participation rates have been dropping off because part time footy players and social players seem to have dried up in many areas too.
It's a lot of work, and it can be done. And maybe they can put to bed some of the BS myths the AFL keep sprouting about their grassroots.
