We alone set indigenous development back 30 years
This controversy is easily resolved with some thoughtful planning on behalf of the AFL ....
The AFL should require each club to publish the full genealogy of each player on their list, so that fans can determine who is boo-able and who is not. The AFL should then publish the selected team's full genealogy each week, maybe on the scoreboard before the teams run out and certainly at the major breaks in the game. Just to be safe, at every interchange, the interchange steward should hold up a card to advise the crowd of whether it is allowable to boo the player who interchanges and perhaps hold up a second card to advise the crowd whether it is permissible to heckle the player who has just returned to the bench.
This then leads to a second issue, which is that some players may consider cheering to be sarcastically motivated and thus synonymous to bullying. An answer may be to swap out the GPS device in the back of each player's guernsey with a mobile phone, which would still provide GPS functionality (provided the player subscribed to the appropriate mobile plan - probably not Vodafone though) whilst allowing players to post their current reactions to the crowd on Twitter, so that fans would know if they've gone too far with their cheering ....
All easily sorted out .....
