With achieved in the VFL and a little * next to them maybe.I'm sure you're right that in its early years the VFL, or whatever it was called then, was simply a local competition with local players, but interstate fans who think it was always just a local competition on a par with the other state comps don't know the history of the game.
As it developed the VFL became the benchmark competition in the land. Nearly all the top interstate talent wanted to play at the top level and joined Victorian clubs. There were a couple of notable exceptions from WA and SA who refused to leave their state competitions, but they were very much in the minority. This made the VFL virtually a national competition for many decades prior to the introduction of true interstate teams and the creation of the AFL. The records of clubs who played in the VFL years certainly deserve to be recognised and their premierships counted.
The AFL is a national competition.
Those premiership should always be remembered but for what they were, state league premierships against 15-20% of the nation's population.
A flag won in the 1950s where some blokes could walk down to Waverly park after playing 14 games with-in tram distance of each other to win a flag is completely irrelevant to something like West Coast traveling 500,000km over 23 weeks against 17 other teams playing games in Tasmania, Northern territory and every other state in the country then playing an away game in order to win a flag.
It's not even close to comparable.
