The biggest difference between then and now is the massive difference in how the game was umpired. There would be a whistle for a ball-up if even just two players were fighting over the same ball and it didn't immediately come out. Not wait half-an-hour for 30 players to run to the contest and jump all over each other. Push in the back was paid even for a slight nudge with the body let alone use of the hands. Holding the ball was paid against ALL illegal disposal. No such thing as prior opportunity either in those days so players would knock the ball on rather than take possession and get caught.
Obviously, a more a positional game back then too so there was little congestion nor defensive/zone structures.
I agree MT. Umpiring was much simpler then.
The other Big difference from then and now is that the interchange was rarely used.
I’m an advocate for KBs call for no interchange bench except for injuries, getting rid of the prior opportunity rule. And teaching umpires to pay the indiscretions as stated in the rule book.
Hold the player off the ball - free kick.
Push in the back - free kick.
You do not dispose of footy by hand or foot when tackled - free kick.
I’m hoping they at least drop interchange to a maximum of 4/quarter as a trial next year.
