Sydney has the best midfield in the competition according to Champion Data’s quality ranking with Josh Kennedy the top-rated ball winner.
The Swans rank third when taking into the account the top six players behind Fremantle and a Geelong side bolstered with the addition of Patrick Dangerfield during the off season.
Richmond and North Melbourne are ranked 9th and 13th overall for midfield quality.
It should come as no surprise Essendon and Carlton have the worst ranked midfields in the competition.
The Gold Coast midfield is ranked 14th in overall quality but 6th when taking in only the best six on-ballers thanks to the Gary Ablett.
