Dunstall's commentary in the Hawks game was ridiculous. At times he would actually exclaim, "oohhh no.." when it looked like Melbourne were about to score. It would've been funny if it wasn't so shamefully biased.
Anyhow, Commetti and Whateley, and you can't go past Bruce, are the ones I most enjoy listening to.
Dwayne Russell needs to be dealt with. He ruins games of footy with his zany catchphrases ("get and go", "outside the paint", "plays for the free", "gives it some toe") etc etc) and complete misreading of the play. It takes a particularly bad commentator to actually ruin a game.
