Haha I did the same Cobbler, when I was about 7-9, for a few seasons, ran my own AFL in parallel with the real season. I remember the Grand Final in the first season in 93, somehow ended up being Hawthorn vs Richmond and Brett Allison won the Brownlow. I wasn't smart enough to work out a proper fixture back then, so I swear that there might have been a few instances of the same teams playing each other 4 times a season. I just threw any old matchup down on paper.
Used to play the matches with a balloon or soft Maccas footy in my room, or in the backyard concurrently with the real AFL matches on 7 or on 3LO. What my parents must have thought?
