Australia coach Robbie Deans has endorsed the new law interpretations featured in the opening two rounds of the Super 14.

But he believes referees must go a step further in order to achieve perfection.

While no changes have been made to the existing laws, SANZAR's directive to whistle-blowers to crack down on the tackler at the breakdown has had the desired effect of encouraging more running rugby and less mindless kicking.

The defender is now required to roll away completely from the tackled player before attempting to contest possession, making it far easier for the attacking side to keep the ball and build sustained pressure.

As a result, the first 14 games of the season have produced a staggering 822 points - 196 more than at the same stage last year at an increase of 14 points per game.

But while the former Crusaders mentor hailed the start of this Super rugby season as the best in recent memory, he challenged officials to now target players who continue to illegally leave their feet at the ruck.

"We're very close to perfection I think, so if they can get the whole picture right and lift the height of the ruck we'll have a great game - and I think we've seen evidence of that already," Deans said at ARU headquarters today.

"Dealing with the first event (the tackle) is relatively easy and having dealt with that they can now turn their focus to the arriving support players and insist that they play the game on their feet, because there is no need now to launch with your shoulders below your hips to remove bodies off bodies.

"So given the referee is going to cater for that, they (players) should be able to enter the ruck higher ... there's still an incentive to go there for both sides so there'll be a genuine contest.

"The risk is if referees don't insist on attacking support players playing on their feet then essentially the defence will opt out of the contest and then we'll end up with a cluttered D-line that we had a couple of years ago."

While the Chiefs' record 72-65 win over the Lions sparked concerns the scales have been tipped too heavily in favour of the attacking side, Deans insists he has no problem with the 18-try affair.

"That was living proof of what is possible if you're constructive," he said.

"If you're prepared to play you've got a chance, but if you're not prepared to play then you're probably limiting your chances.

"But clearly the Lions were in a context where they were out of the game so they had no choice but to be constructive, be positive and try and carry the ball.

"Possibly the Chiefs contributed to it because they were so far ahead they didn't feel the need to contest and resist to the same extent that they might have if it was tight, but the outcome from a spectacle perspective was great."

Meanwhile, Deans confirmed the upcoming Tri Nations series between South Africa and New Zealand will be played under the new law interpretations, and is hopeful they will also feature at the 2011 World Cup.

And in a sign the former All Black will be granted his wish, Deans revealed the new interpretations will be adopted during upcoming Six Nations clashes that feature southern-hemisphere referees.

"I understand from some conversations I've had that our blokes who are going up to referee in the Six Nations have been instructed to referee exactly the same way that they are here," he said.
