The motto of the Handy Prem is/was 'where All Whites are made". And to a reasonable extent it was doing that. The Eastern Suburbs title winning side of a few years back being one strong example.
And if not producing AWs then a steady stream of guys, getting scouted and being signed by overseas clubs. Joel Stevens went to Sweden from Southern. Yipe he'd already been to Sweden once before, and prior to that with Weenix/TW.
But fact is he was playing National League for a franchise based in Dunedin, and from there got picked up by a pro club in Scandinavia. So he's an example for Otago/Southland footballers that if they stayed local for their national league football (Southern United), they could end up overseas. Erik Panzer is another guy that from Southern, has got a few overseas 'pro' gigs.
As GM says the chances of a Southern League side progressing to the end of season playoffs, past all the Mainland League sides looks slim at the moment. Will a young player be noticed playing in the obscure, lower quality Southern League. Unlikely. Sure is a high chance he would have gone to ChCh, Wellington or Auckland anyway (if just for his winter football) - but now that's 100% given, I reckon.
Of course Southern United, ain't in this year's Handy Prem. Would they have managed to survive if not for Covid, I don't know. Without a forensic look over their financials no one can 100% say for sure. For awhile there, their model of having a few overseas players (Irish) in as regional football development officers, plus playing for Southern in the Handy Prem looked reasonable. From what I'd read they really lifted the amount & quality of kids coaching, in the Southern region. Maybe I missed something (likely) but I'd never heard reports of financial problems down there until Covid.
And yes you can agrue until you are blue in the face, that technically the National League starts in March. But apart from a few NZF officials is anyone else, really going to think like that. When you are just playing other Northern, Central, Mainland or Southern clubs through the colder months as per every other winter season.
Anyway NZF have made their decision, let see what happens.
