Port Adelaides great Kane Cornes says three club captains need to improve and do it quickly.

Cornes has said targeted GWS' Stephen Coniglio, Adelaide's Rory Sloane and Hawthorn's Ben Stratton.

โ€œCaptains are on the agenda today. Iโ€™ve got three of them in my sights for differing reasons and two of them are new captains so weโ€™ll give them a bit of grace that theyโ€™re adjusting under tough circumstances,โ€ he toldย SENโ€™s Whateley.

Coniglio was given the role at the end of last season after signing on to stay at the Giants and has had a more subtle output compared to his usual lofty standards.

โ€œIโ€™m watching Stephen Coniglio play and heโ€™s not the player weโ€™ve seen over the last three or four years,โ€ he said.

โ€œNow, pressure of a big contract, new captaincy โ€ฆ as simple as this sounds, he doesnโ€™t want to kick a drop punt.

โ€œI was watching him play against Port Adelaide and he was picking the ball up and heโ€™s in field positions kicking check-sides and snaps around the body instead of kicking drop punts so 46 per cent kicking efficiency.

โ€œTheyโ€™ve thrown him around the place to try and get him involved, but heโ€™s not having the influence that he should for a player thatโ€™s paid as well as he is and for his standing in the game so thereโ€™s some pressure on him to respond.โ€

Cornes believes Sloane is also having a down year, but it comes in a year his club can ill-afford it. The Crows are winless and occupy the bottom of the ladder and haven't looked like winning a game so far.

โ€œRory Sloane has been all at sea. Now, heโ€™s banged up," he said.

โ€œIโ€™m not sure heโ€™s come into a game with a full bill of health, but Iโ€™m yet to see him really have any moment where he can drag his team along and make a statement for a team thatโ€™s under fire.

โ€œYear on year his form is really down.โ€

Lastly, Cornes turned his attention to Hawks skipper Stratton. Hawthorn have been up and down this year and Stratton is leading out the AFL's oldest list.

โ€œIt was a questionable choice as captain at the time and I think that remains to be seen.โ€

โ€œIโ€™d just love to see them turn over a new leaf. James Sicily is the man for me. Make the call for him to lead them for the next five to six years.

โ€œHeโ€™s not perfect, but Iโ€™ve loved his development. I see him with a similar temperament to a Jack Riewoldt who had some moments in his career when he was younger โ€ฆ Sicily, his development is what Iโ€™ve loved.

โ€œHeโ€™s improved a lot and I think he has the fire in the belly, the leadership and the brilliance to be the captain of that footy club.

โ€œItโ€™s a risk, but heโ€™d be the one that Iโ€™d go to.โ€
