North Melbourne CEO Ben Amarfio has invited club legends to "come into the club (and) be part of the solution" after stinging criticism from Wayne Carey, David King and Corey McKernan.

The Kangaroos' brutal year on-field has been replicated off it, with the sudden departures of national recruiting manager Mark Finnigan and list manager Glenn Luff this week - and national recruiting officer Ben Birthisel last week.

While general football manager Brady Rawlings confirmed that Finnigan and Birthisel were expected losses, which the club had known about for weeks, the departure of Luff seems to have taken the club by surprise.

“Glenn did inform us today of his resignation. He’s a great operator, Glenn, loved his time working here with me and for us. He’s decided to pursue other opportunities," Rawlings said on SEN.

The near-simultaneous departure of three key members of North's recruiting team led to biting criticism from the AFL community, including Shinboner immortals Carey and King.

"This is as low as this football club has been since I've known it," Carey told Triple M.

"I don't think they are being completely honest with themselves because you can't improve until you actually acknowledge that we are don't have people just resigning for no reason".

King was less damning than Carey, acknowledging that the issues facing North Melbourne make it "hard to watch," but affirming his belief that the club would respond.

“Nothing changes really (following the departure of the recruiters) – the footy club moves on...if those issues are genuine, which I think some of them are, we’d be silly to say everything is fine here, nothing to see," he said on AFL360.
