Joel Selwood and Nathan van Berlo compete for the ball.
IN the wake of Phil Walsh’s death, Sunday’s Adelaide-Geelong clash has been cancelled, resulting in changes to SuperCoach Round 14 in-game scoring.
The decision has been made to go back to the top 18 scorers as it was during the bye rounds.
Several popular players will be unavailable this week and we believe this is the best way to reduce the impact.
Below is the rules for the bye rounds, as explained in the game’s terms and conditions, which will apply for this week.
In rounds 11, 12 and 13, a participant’s score for the round will only be based on the scores of the 18 highest scoring players of their selected starting 22 players (including any emergencies which replace those players). Participants will still be required to select 22 starting players in rounds 11, 12 and 13, and if there are more than 18 scoring payers in their selected 22 players, only the scores of the top 18 scoring players be used to calculate the participant’s score for that round.
