7. Brayden Maynard

This fearless defender once again proved his worth to the Pies in season 2020 as the side was plagued by injury troubles. The 24-year-old didn't miss a game for Collingwood, with impressive stats in a defence which was third best for points conceded. Maynard averaged 387.8 metres gained per game, 6.2 intercept possessions per game as well as 10.3 effective kicks per game - all elite numbers for the league.
