The big difference between a team like Melb and team like Perth is mental toughness.
On paper Melb is star studded, but what you don't see is how well they gel, what their team morals are and how they work together as team in the face of adversity.
Hate the wildcats all you want, but whene it comes to on court mental toughness you won't find a stronger, tougher collective unit tougher than Martin, Hire, Wagstaff, Knight.
While these four aren't the superstars or major contributors to the team anymore, they are the nucleus that drives it, and it extends to the new recruits. Kenny, Walker, DKD and the imports have all bought into it. It's also the reason Cotton came back.
When the ship begins to topple you can count on this core to keep it stable and make sure everyone is mentally focused.
Melbourne doesn't have this and it will be their downfall.
CG43 for all his talent, is not the mentally strong leader to set the tone for a team. He himself, reacts to refs and complains, a lot. If that is your leader then everyone else will follow suit - and it's shown to be the case so far.
I also think Adelaide will be the next Perth, with their young core of Aussies who have come up together and are developing their own culture.
