Quotes from the people involved

“I’ve given everything I have to this club. I’ve loved every minute of it, but now it’s time to put my family first.”

— Mitch Duncan, via Geelong Cats statement (Geelong Cats)

“We are thrilled to welcome Mitch and his family to the West Coast Eagles. His experience and leadership will be invaluable for our young backline group.”

— West Coast Eagles official statement (West Coast Eagles)

Mitch Duncan’s journey from a 305-game Geelong legend to West Coast’s backline coach is a story of deliberate timing. He walked away at 34, not because he couldn’t play, but because he chose family. For West Coast, the gain is a premiership-winning mind to shape their defence. For Duncan, the move brings him back to Perth, where his career began. The implication for the Eagles is clear: they’ve landed a coach who knows what it takes to win a flag, and who will be motivated to build a similar legacy on the other side of the country.

Many Geelong fans were surprised by Mitch Duncans move to West Coast, but his leadership qualities made him a natural fit for the Eagles’ coaching panel.
