@ Humpers and the Psych
You mention changes that have boded well.
Geelong - champion side loaded with talent including a host of duel premiership players. Bomber Thompson didn't want to be there anymore, and Brad Scott admits he pretty much walked in to the easiest gig in the world where the players all but ran the entire show. Also a hell of a lot of luck in 2011 with their close wins earning them a top 4 finish.
Adelaide - Neil Craig was there for 7 seasons, never got them to have an impact in September, and had not one but two horrible seasons before they cut the cord. It wasn't one step back but a sustained fall that had them lose faith. Also interesting to note that Craig was famous for how well drilled they were; for how solid and clear their game plan was. Sanderson has been described as letting them off the leash. Moreover, it's a little early to call it a complete success. There's a way to go, and they also had the
best draw for 2012.
Freo - Mark Harvey was never any good, the dockers only ever had one decent year under him. Then the best coach in the AFL was up for grabs. No brainer to switch. Mind you, not all dockers supporters were too pleased with him before their recent patch of form. Also a bit early to call an obvious success.
Collingwood - neither of you mentioned, but Bucks was there all through Malthouses rein and thus had the smoothest transition imaginable. Also took over a premiership side who only just missed out last year.
Compare that to all the changes that have lead hitherto unsuccessful rebuilds
-Every Richmond coach for 30 years
-The Dogs sacking Eade. Look at them now.
-Primus at Port. That worked well.
-Melbourne sacking Danniher and then Bailey. Masterstrokes.
-Voss (

)
-Knights and now Hird
-The other Scott brother has only just got them playing finals
And then think of the times when the pressure has been on and the club sticks firm, only to see results
-Bomber Thompson famously in 2006
-Clarkson every season since 2008
-Worsfold after 2010
