The only question mark now hovering over Port Adelaide this season is its biggest.

Saturday's one-point win over Brisbane at the Gabba confirmed the Power was the best side this season and was headed for its second-straight AFL minor premiership.

But in two months' time, Port will have to overcome the reputation it developed over the last two years as a finals choker.

While Port also beat the two-time defending premier in round 22 last season, this 15.14 (104) to 15.13 (103) success could prove much more important.

The implications are certainly dire for the out-of-form Lions, who dropped to sixth and have won only two of their last seven games.

Brisbane lost five games all season in the last two premiership years.

The other top-eight loser this weekend was Fremantle, which stayed seventh despite fading in the last quarter against Sydney at the SCG.

The Swans responded to a rare three-quarter time spray from coach Paul Roos to overturn an eight-point deficit and win 17.9 (111) to 14.13 (97).

But the win came at a cost, with key ruckman Jason Ball dislocating his shoulder and out for next week's clash against Adelaide.

The Crows have one of the AFL's best ruck duos in Matthew Clarke and Rhett Biglands.
