Yes, I hope you are funding all your top imports, yes there is always the Cotton, Adams, out there but they start at the 500g mark plus house, car etc.
yes there are a few Australian players that are not to standard, they normally have family or in the know connections but overall the balance between imports and Australian is right.
There are some scrubs as you call them in the nba as well, Deng Adel was supposed to be g league star, I can see you enjoyed watching him last season. Hannah was going to be the shooter ever seen in Australia, g league stats told us that, yep that worked.
Adnam is probably on 80/100g year bracket, your man Hannah is probably on around 250g plus car and house and you want five of them in each team.
Do the calculations, most clubs can't afford the Cotton and Adams of the world, Perth have been so great because they nurtured Australian talent with a good Australian coaching, bevo, Gleeson, that is now slipping and even Cotton is struggling to save them.
