North Melbourne great Wayne Carey has ripped into the club's star forward Ben Brown after his slow start to the season.

Brown has bagged just six goals so far this season amongst the team's struggles, sitting winless in 17th place.

Carey described the Kangaroos' 16-point loss to Hawthorn on Sunday as "atrocious", lamenting basic skill errors.

“They can’t fly under the radar anymore — they were atrocious (against Hawthorn),” he said on Channel Seven’s Talking Footy.

“The problem with the Kangaroos is if you can’t hit a target from 30 metres away, when that player is 30 metres clear … those skills are deplorable at the moment.

“They have no excuses, the Kangaroos, they’ve recruited really well.

“They were as poor as any team.”

The AFL Hall of Famer pinpointed Brown as of one of the Roos' underperforming players following his one-goal effort against the Hawks.

“Ben Brown has to look at himself in the mirror and ask himself whether he wants to be a star of this competition or one-dimensional.

“If he doesn’t mark it, he’s deemed useless — he has to get a couple of other tricks up his sleeve.”

Carey added that opposition defenders have learnt how to defend Brown and that he must add another element to his game.

“Defenders now know if they get the ball to ground on Ben Brown … he’s not going to put any pressure on — he didn’t lay any tackles — second and third efforts that’s what he needs,” Carey said.

North will look to get their first win on the board this season when they host Adelaide on Saturday night at Marvel Stadium.
