Under the Jack Dyer Medal voting system, all of the team’s players on match day receive a rating from 0-5 based on their overall performance.
The match committee assesses each player’s offensive, defensive, and contest impacts on the game.
After those game phases have been analysed, the 0-5 rating is given, as a joint match committee decision.
Votes are not allocated for what the match committee deems a below-average performance.
