HAWTHORN defender Campbell Brown has given cautious support to the AFL's new rule that penalises deliberate rushed behinds, but has pleaded for a longer trial period.

The rule to be tested in the NAB Cup will see a free kick awarded for a rushed behind and it could continue into the home and away season if deemed a success.

But that would be moving a little too quickly for Brown's liking.

"I think we've just got to get used to it. The NAB Cup will be a good introduction to it and hopefully they give us a couple of years before they bring it into the regular season," Brown said from the Hawks' Telstra AFL Community Camp in Hobart.

"But I think it's a really good idea and will make the game a bit quicker and we might see a few more goals.

"It's going to be interesting [though because] I think early days we're going to see a number of defenders forget [the rule].

"We're not the brightest guys. That's why we're probably playing down back."
While many of his counterparts across the competition have voiced their reluctance at gradual changes to the defensive game, Brown felt the latest move – though difficult to accept early – could prove a winner long term.

"We're running out of friends aren't we? We're just going to have to take the game on a little bit more down there and we're going to have to take risks to bring it out of the backline," he said.

"Sometimes it will create goals for the opposition, but that's just life now I think.

"I don't think they're clamping down too much. I think everyone likes to see a free-flowing, high-scoring game and the AFL are trying to bring that in.

"It took a while for players to get used to the hands-in-the-back law and there was a lot of argument from the backline. But now after it's been in for a couple of years, we've learned to adapt to it and you've just got to try and come up with other ways to stop your opponent."

Brown also took the opportunity to reinforce the focus of his club since pre-season training started last November.

"You could live the rest of your career looking back at [the 2008 premiership] and we don't want to do that," he said echoing the views of coach Alastair Clarkson and Sam Mitchell.

"We're here with a job to do again in 2009 and I think there's a good chance for a lot of young guys to step up into the side that didn't get the opportunity last year. We're really trying to put that out of our minds.

"It was fantastic and everything, but it's a long time ago and we mean business."

Hawthorn's community camp will conclude on Thursday with the squad split between Hobart and its surrounding areas, and Launceston.
