Buckley is good, very good, but not as great as the Collingwood hype machine has made him out to be. He will always be a level below the Hird's and Voss' that he is always compared with.
Overrated - Tarrant, Richardson, Stephen King definately. I would have said Primus but he's retired anyway. Have never thought Wanganeen was that great either.
It's funny, some of the names coming up you could make a fair arguement for being overrated. Clement is a good one. He's a very talented footballer, a well spoken guy, you'd love to have him in any team. As a footballer he is certainly not overrated. But the automatic AA selection (and the fact that he plays for Collingwood) brings his rating into question. It's the same for Buckley, if he played for anyone else (except maybe Port, equally as bad at pumping up their own) he wouldn't come into the equation as being overrated.
