More broadly the biggest issue I see is there is still lack of decent Australian talent. Add 2-3 more teams and it makes the quality of teams go down.
Conversely though, the small number of teams, combined with now having 3 imports, combined with having games only 40 minutes long, means limited opportunities for the younger locals I reckon.
Some Cats fans earlier commenting on the lack of progress with Kernich-Drew, which I agree about, but I think it's largely lack of opportunity. On one hand I wish we played him more, but on the other hand I get why we don't.
Spending multiple years getting only token minutes because the stakes are so high if you make a mistake, stifles the development of players IMO.
So there's a tradeoff necessary between having a super-strong league, and one that gives real opportunities to developing players.
