RICHMOND forward Jack Riewoldt says the young Tigers forward line that he is a key part of is coming along well.

The Tigers play St Kilda at Docklands on Sunday evening, which means not only does Jack face superstar cousin Nick, but the Tigers come face-to-face with the league's stingiest defence.

The Saints have given up just 728 points over their 12 games so far, nearly one hundred better than joint ladder-leader Geelong and two hundred better than the third-ranked Collingwood.

When you're only 12th for points scored, as Richmond is, the challenge is clear, and Riewoldt said the group was keen to take it on.

"They're a great defensive unit, the statistics show you how well they defend together," he said before training at Victoria Park on Thursday.

"It's obviously a good challenge for a young forward line group to go out there and hopefully try and win a game for us and kick a score.

"The eight guys that go through there on the forward line are really looking forward to it."

Riewoldt, who has kicked 13.10 from his 10 games this season, said the attacking set-up was coming along.

"We've probably been developing for about a year-and-a-half now, even since that Fremantle game in round four last year when Richo (Matthew Richardson) moved up to the wing.

"We've got a few new faces down there – Robin Nahas is down there and he's been lively and has had a great input, Tommy Hislop last week played a fantastic game, along with young Tyrone Vickery.

"We've got a lot of young faces down there, and Mitch (Morton) is almost the oldest person in the forward line, so we've got a lot of new guys down there, a lot of exuberance, a lot of youth.

"We're just trying to do our job best for the team – put on defensive pressure and hopefully kick a winning score."

The 20-year-old said he probably wouldn't be talking to his cousin in the next few days, and football isn't usually topic of conversation between the two anyway.

"Not this week, I wouldn't talk to him – generally when we do talk, we don't talk about footy, it's more just seeing how each other is," he said.

"If he picks up something in my game that I can fix he generally lets me know, so he's a great help like that, but I suppose in a week like this we'll just go our separate ways and have a chat after the game."
