Former West Coast coach John Worsfoldsaid on Monday introducing zones had been raised at a recent Laws of the Gamecommittee meeting but it was considered, at this stage, an impracticalsolution.

Roos laughed at the suggestion, saying if itwas introduced, the game would be so different it should not be called footballanymore.

"If we want to keep it as football wekeep it as football. If we want to play a different game then you call itsomething else and we'll play a different game," Roos said.

"We can have two games – one AustralianRules Football and have one called zoneball – that is a great idea."

Roos said the current game was good to watchand was evolving to a more one-on-one style. He said the concern aboutcongestion was an overreaction.

"We were talking about the flood yearsago, and that went away. We were worried about the zones and then that wentaway and now we have got one-on-one football," Roos said. 

"If you watch the game closely, the gameat the moment it is as close to 18 one-on-one contests as you can possibly haveand we still have people complaining."

Roos said he couldn’t remember a time whenevery match was sensational but in general terms, the game was tracking well.

He suggested the biggest change was theintroduction of two extra teams, which spread the talent.

The introduction of Gold Coast and GreaterWestern Sydney means 100 extra players play AFL each season.

While he was at it, Roos said the Match ReviewPanel's inconsistency remained a frustration but he acknowledged it was a difficultjob.

He suggested the MRP could create a bank ofvision showing low, medium and high impact hits to draw upon when assessing andgrading particular hits.

Melbourne's key forward Chris Dawesmissed Saturday’s clash against Port Adelaide in Alice Springs after beingsuspended for one week for striking. His contact with Richmond's AlexRance was assessed as medium impact.

Dawes said he was reluctant to criticise theMRP’s decision in his case because he put himself in that position and had tocop the suspension.

He admitted he carried a personal bias becausehe was suspended but he said he there was too much risk attached to playersdefending themselves in front of a tribunal in such circumstances.

"My biggest concern is that it is asystem where I couldn't defend myself. I couldn't risk getting a second week ontop of the one that I ended up taking with the early plea," Dawes said.

He said assessing impact had become toosubjective.

"It needs reviewing and it will bereviewed but I don't want to criticise too much because it was brought in withthe right intentions and I'm sure they will come in with a more workable systemtowards the end of the year," Dawes said.
