TWO OF the competition's heavyweights continue to feud, with Collingwood president Eddie McGuire saying Geelong counterpart Colin Carter's move from the AFL to the Cats was "the biggest conflict of interest I've seen".

McGuire's view that the Cats be transparent over Jack Steven's stab wound was met with a blunt response from Carter this week, who suggested McGuire would apologise for his comments about a rival club.

However McGuire did not back down on Saturday.

He said Carter, who was a Cats board member from 1988-1993 ahead of being appointed to the AFL Commission, before then rejoining Geelong in 2008, had knowledge of the inner workings of other clubs. Carter took over the Cats' presidency in 2011.

"Why would I apologise for? I wouldn't think so," McGuire told Fox Footy.

"I would say in my time in the game that Colin going straight from the AFL Commission onto the Geelong board and becoming the president of Geelong was the biggest conflict of interest that I've seen ... but no one writes that because there’s no clickbait involved," he said.

"He had over 15 years of understanding what the AFL's strategies were, he had access to every club's business plans, all that sort of stuff."

Cats coach Chris Scott held a press conference on Thursday but revealed few details about Steven's incident last weekend, which is under police investigation.

McGuire again questioned the worth of holding a media conference without offering answers.

"If you don't want to have people guessing at a situation, there's one of two things you do," he said.

"You don't have a press conference and you don't say anything until such time as you can, or you come out and say it.

"I don't think that's revolutionary in the world of PR or broadcasting."
