I personally disagree.
I feel Kennett's comments were directed at the state of umpiring rather than at the inidividuals who adjudicate the rules - i.e. he was aiming his comments at the AFL forcing the umpires to pay rubbish free kicks that are often very incosistent (for instance, what the bloody hell is going on with the 50 metres penalty for holding someone after they get rid of it? It gets paid probably 1 every 4 times, the other three times the umpires pay a down the field free kick).
The AFL has brought this criticism on itself. If it doesn't want its rules to be challenged, it should stop bloody changing them. The more they tinker and change, the more people get angry and start pointing the finger.
No offence but comparing AFL umpires to Rugby Union umpires is almost impossible. Rugby Union umpires adjudicate a sport with minimal rule changes and are instructed to use only players numbers and shirt colours when talking to the players - they deserve respect because that is what they demand. AFL umpires are unnecessarily "miked" (sp) and instructed to adjudicate a set of rules that seem to change each week whilst calling players by their not only their names, but their nicknames! How can an official demand respect when they are calling players by their affectionate name?
