BRENT Harvey denies North Melbourne still relies on him too much in close games, saying the Roos have a spread of players they can turn to at crunch moments.

Harvey turns 36 next month, but is yet to show any signs of his age on the field.

Last Sunday, the five-time best and fairest winner sparked the Roos to a 29-point win over the Western Bulldogs, helping to bring a dull contest to life after half-time.

In a defensive contest where congestion reigned, Harvey was the difference.

He found space where others ran into human walls and finished clinically where others butchered their opportunities.

In addition to kicking three goals from the 28-minute mark of the third term, Harvey had 25 possessions, three goal assists, five bounces and six inside 50s.

It was a performance that was impossible not to acknowledge, but some commentators expressed concern North had again turned to its oldest player to get it over the line.

Harvey, however, told AFL.com.au on Monday the Roos had no cause for concern.

"I'm part of the 22 and if they need to rely on me that's fine because what you find is one week Lindsay Thomas kicks four, the next week he gets shut down and somebody else needs to step up," Harvey said.

"So it's not always going to be me, it's not always going to be Daniel Wells, it's not always going to be Drew Petrie.

"I think we're no (more) reliant on me than we are on Ben Cunnington and Jack Ziebell to win the ball in close."

Harvey was just 21 when he played in North's most recent premiership in 1999.

The speedster ran out that day alongside North greats such as Wayne Carey, Anthony Stevens, Glenn Archer, Mick Martyn and David King.

Asked whether North's core of young players would ultimately be good enough to emulate the feats of Carey and co., Harvey said it was "a tricky question".

"If you answer it is, everyone starts thinking, 'Righty-o, you're going to win a premiership'," he said.

"It's a lot harder than that. My mindset – and I hope I've got 21 other teammates running out with me on the weekend (thinking the same thing) – is that we can win every single game.

"If that happens you put yourself in a position to play finals, number one, and then hopefully to win a premiership."

Of North's youngsters, Harvey is confident Shaun Atley can take another step forward in his fourth season, says 2014 debutants Luke McDonald and Daniel Currie have looked at home in the AFL, and backs Kieran Harper to bounce back from a disappointing 2013.

North has made a relatively slow start to 2014, its scoring output a long way down on the previous two seasons when it was the third highest scoring team in the competition.

Harvey said that was partly because his team was still adjusting to a "slightly" different game plan with a stronger defensive focus.

But he was confident the Roos could get back to their best soon.

"I think we've just got to attack a little bit more and take the game on a lot earlier," Harvey said.

"I think we did that in the second half on the weekend, but I think we can do that in the first half and try to maintain that."
