“We set out to appoint a team of coaches who complemented each other, a group of diverse football thinkers and relationship builders who have also shared in a lot of success that could mould our young squad. With the appointments of Justin and Brendon I think we’ve gone a fair way to doing that,” Collingwood football boss Graham Wright said via the club's announcement.

“We see that Justin’s and Brendon’s attributes complement our profile well. Approximately half of our list in 2022 will comprise of 1-3 year players. The football education we provide them, therefore, will be important.

“Craig is very strong on establishing habits that will underpin a collective approach to success. We are all really pleased to have Brendon and Justin join the program.”

The Magpies have looked to part ways with interim coach Robert Harvey since the season's end, while Brenton Sanderson is tipped for a new role at the Holden Centre.
