2021 AFL season: Round 7 preview A Set the default text size A Set large text size Replay A Set the default text size A Set large text size A quarter of the season has already passed and only two teams stand undefeated: the Western Bulldogs and Melbourne. While both the Dogs and Dees should start favourites to extend their unbeaten runs this weekend, they do face some tricky opposition with the Dogs facing a Dusty-less Richmond at the MCG and the Dees tackling North Melbourne in Hobart, though that match could yet be moved to Marvel Stadium. Elsewhere, the Gold Coast Suns will fancy themselves of winning just their fourth match at the MCG when they face second-from-bottom Collingwood, while the Brisbane Lions will start hot favourites against Port Adelaide at the Gabba in the evening.
