IT HAS been a tumultuous nine months for Collingwood.

Between a thrilling one-point victory over West Coast in the 2020 elimination final, and a thrilling five-point win over Adelaide last week, the club has been challenged and faced justified scrutiny both on and off the field.

Change, both in the playing group and among the football department, has been vast and significant. The resignation of Nathan Buckley on Wednesday, the club's senior coach for the last nine-and-a-half seasons, being perhaps the most important departure.

In the wake of Buckley leaving, here are the key moments from a brutal period for the club.

A disastrous Trade Period sees important trio Adam Treloar, Jaidyn Stephenson and Tom Phillips depart the club for little return. Young defender Atu Bosenavulagi also leaves.

Collingwood's 'Do Better' report is released, finding "systemic racism" within the club "that must be addressed if things are to change".

President Eddie McGuire receives criticism after labelling the release of the report a "historic and proud day" for the football club.
