Geelong assistant coach James Rahilly is leaving the AFL runner-ups to join wooden-spooners Adelaide.
Rahilly is departing after a decade at the Cats to be an assistant to the Crows' head coach Matthew Nicks next season.
Nicks will have a new-look batch of assistants with Scott Burns (Hawthorn) and Nathan van Berlo (West Coast) also joining his team.
Nicks' sole remaining member of this year's assistant coaching staff is long-serving ruck coach Matthew Clarke.
The Crows have parted with assistants Ben Hart, Michael Godden - who will take over as coach of the club's state league team from next season - and Brent Reilly, who has returned to a development coach role.
Nicks has appointed a new football and data strategist with Chris Sheedy joining the Crows from Port Adelaide.
Adelaide this year finished last for the first time since the club's 1991 inception.
