Both Geelong 1995 to 1999 and Adelaide 2000 to 2004 had mature lists and good players. Geelong wins went 16, 13, 15, 9, 10. Joe Bloggs could have taken over the Cats after Blighty and delivered those numbers. Adelaide went 9, 12, 15, 13, 8 (with several of those last 8 wins attributable to Neil Craig). See Geelong. He obviously could not, ahem, get the job done at either club and eventually lost the players at both; spectacularly so at Adelaide. Nor has he had any experience developing young players at either club. And nor does the VFL count. An experienced coach with a good list should be able to show good results at a lower level. And, and nor has he displayed any great talents in the media, for what that is worth, apart from a talent to spout clichés and refer to his players in the plural.
As an aside, lets see how Chris Scott does when the Geelong champs (Scarlett, the Coreys, etc) pull the pin.
