This is probably more for the Aussies, but if anyone knows of any other realy **** commentators - throw 'em in.
The commentator I reckon is the worst is Ian Chappell. For a guy who knows so much about cricket and could give so much insight into the game he spends so much time talking about absolutely nothing.
He can spend over half an hour talking about a batsman's grip or a crack in the pitch, someone in the crowd, anyway you get my drift.
Other candidates - Mark Taylor, Shane Warne, Simon O'Donnell, Mark Nichollas (sp)
We all know who the greatest of all is - Kerry O'Keefe. And I have been impressed with Harsha Bogle (sp?) and Greg Chappell.
