Yeah, you're right TM.
Have done a bit more research this AM and came up with this.
Note that the club website has only as far as 2010 full Annual Report, listing staff (maybe if someone keeps them?)
2007 Bulldogs - Part time forward coach
2008 Bulldogs - Full time midfield coach
2009 Richmond - Full time midfield coach. Last year of Wallace with Rawlings as caretaker
2010 Full time midfield coach? First year of Hardwick with Daly as Forward coach, Lade as stoppage coach, Leppitsch as Defense coach.
2011 Not sure but I have a feeling he swapped with Daly.
2012 Opposition analyst and Leadership Development. Williams joined from Melbourne as forward coach, pushing Campbell out
2013 opposition analyst, Leadership and Manager of VFL strategy.
In this Age article from December, it says
"For the past 18 months, he has played a leading role in putting together Richmond's stand-alone VFL team."
So it's clear that Campbell hasn't had a direct coaching role for at least two years before he left.
