IT'S THE pivotal duel between two versatile key-position players that could determine whether West Coast or Melbourne advance to the Grand Final.

Those standings are based on the Schick AFL Player Ratings, which are calculated by Champion Data and take into account an individual's past 40 games over a rolling two-year period.
