I'm happy to admit there is value in shedding more light on the earliest history of the game.
It's a stretch to suggest that this means VFA Premierships should be considered VFL/AFL Premierships; I could even argue it would be doing a disservice to the actual history if you were to do so.
If the book contains some compelling argument to the contrary, feel free to summarise it and if it sounds like it may have merit, I'll gladly add it to my reading list.
