Port Adelaide are not premiership contenders, according to former Hawthorn premiership player Campbell Brown.

The Power sit top of the ladder, winning 10 of their 13 games, but Brown believes they have reached their peak and were found out against Geelong last week.

โ€œI think (Port Adelaide) are done and dusted,โ€ he said onย SENโ€™s Dwayneโ€™s World.

โ€œI think they might struggle a little bit, they really got found out last weekend against a top notch Cats side.

โ€œThey lose a couple of players due to the COVID restrictions โ€“ [Peter] Ladhams has been pretty serviceable and [Dan] Houston has been a star on the half-back line.

โ€œThey need to get a few more options up forward because if Charlie Dixon doesnโ€™t play well, they really struggle forward of centre.โ€

Brown named Geelong as his premiership favourites, ahead of Richmond, West Coast and the Brisbane Lions.

โ€œRight now where we sit I think only four sides can win it,โ€ he said.

โ€œIโ€™ve still got the Cats as the favourite no matter where the game is played.

โ€œIโ€™m very confident the Grand Final will be at the Gabba and it certainly gives the Brisbane Lions an advantage as well.

โ€œRichmond obviously are starting to build pretty nicely and the West Coast Eagles (are the other team that can win it).โ€
