Across the past eight decades there has been more and more meddling with the rules:
- 1940's - Three rule changes, the most significant being the use of two reserves, the 19th and 20th man, from 1946.
- 1950's - Four rule changes, introduction of runner carrying coach’s message from 1955.
- 1960's - Six rule changes, flick pass banned in 1966.
- 1970's - Five rule changes; centre diamond in 1973, centre square from 1975 and interchange from 1978.
- 1980's - Six rule changes, 50-metre penalty introduced in 1988.
- 1990's - Fourteen rule changes, “prior opportunity” written into holding-the-ball rule in 1996.
- 2000's - Twenty-three rule changes, minimum length of kick that qualifies for a mark increased from 10 to 15 metres in 2002.
- 2011 on: Twenty-five rule changes, 6-6-6 formations at centre bounce introduced in 2019, kick-in rule also changed.
And you can guarantee that from the 1990's onward as the corporate side of footy grew and expanded so to did the adjustments n modifications to the rules expand. Flogs in suits on big fat incomes need to do something to justify their existence so rather than let the coaches work out ways to win games and premierships, it's now up to the manipulators at HQ to constantly adjust the way the game is played n effectively shut down any tactical advantages as soon as a trend is identified as being successful.
Always takes a side two or three years to modify their list to suit a game system a coach may want to implement. If the new system is unsuccessful then it's usually not long afterward that a club starts searching for a new coach. If the system is successful then after a couple of years opposition coaches start working out ways to block the system or copy the system to re - balance the comp until such time as the next coach makes a successful new adjustment.
AFLHQ loathes and detests any club being successful for more than a year or two as they desperately want every club in the comp playing finals on a regular basis and vying for the chance to win a flag. It's part of their ingrained socialist manifest of operations. Hence the constant fiddling and manipulation by the flogs in suits, all for the greater good of the competition of course.
