When is a rebuild actually complete though? Carltons rebuild is not complete. Neither is the Saints. Richmond havent stopped building either and they've won 3 of the last 4 flags.
No one knows, it’s not like there is a press conference to announce it or any actual measure for it.
I think once you believe you have a finals team and adding parts to it to try and make it a flag side, is when you have finished rebuilding.
So by my reckoning:
In contention/thinking they’re in contention: Richmond, Geelong, Brisbane, Port, St Kilda, Melbourne, West Coast, Bulldogs
Renovating/hopeful of finals: Collingwood, Carlton, Fremantle, Sydney, Gold Coast, GWS
Rebuild mode: Essendon, Hawthorn, Adelaide
Ground zero: North
The above is where each club sees themselves, though obviously some in each bracket could be proven delusional in terms of where they are at.
I had to create a different category for north.
