Reserve teams need to be kept out of WCL, this is a non-negotiable for me. I'd be ok with the Nix U18's being in there, but that's it.
I expect the league will be an NINE team league. Nix U18, Petone, PNU, Seatoun, Miramar, Vic Uni, Marist, Napier City Rovers (promoted from Central Fed League), & Te Kotahitanga (promoted from Cap Prem).
It'll be initially 9 teams, because I suspect there are some serious fears about Marist not having a team to enter. I'm not a Palmy local, but the rumour is they're losing more players this season (a few are moving cities I believe). I was told their academy players probably aren't ready for WCL either, so unless they can convince the veterans in their "Mayhem" social team to step back into Central League, their firsts are in serious trouble.
In other words, it'll be a nine team league to cover the risk of Marist withdrawing.
Also, I'm not sure any other club is ready to step to WCL. The next highest Fed League team is Moturoa, who pulled out end of last season and have a 2 year ban in place as a result, while below them is New Plymouth Rangers in 3rd. They'd probably say yes to promotion, but is their squad good enough for it? From Cap Prem, next highest eligible team is Wairarapa United in 5th (North Wellington could move ahead into 5th on the final day though). Both of those teams have HALF the points Te Kotahitanga do though....not sure they'd be ready for the league either. Unless we accept there will be one season of "adaptation", where the bottom 2 or 3 might might be some distance off the rest?
