This is the final edition of the Open Power Rankings for the 2018 season. The list was formed by a panel of 12 individuals, spanning all regions, who discuss the top contenders and then vote on the contenders. Panelists then rated teams on a scale of 1-10, with the best team on the contender list given a “10” and the worst given a “1”. The highest and lowest score for each team was removed before averaging the final scores. These rankings were focused on the teams' bodies of work over the 2018 season.
