ADELAIDE expects a low-scoring game full of intense defensive pressure against Fremantle today - and is banking on injured Taylor Walker to be one of the keys to unlock the Dockers. Walker can't do anything physically; he is still hobbling around on crutches. But assistant coach Mark Bickley yesterday had the key forward pass on hints to Adelaide's inexperienced key forwards on how to deal with the strangling Dockers. There is not a 50-game player between Josh Jenkins, Shaun McKernan and Tom Lynch. Sam Kerridge, who slotted six goals in his breakout seventh AFL game, is even greener. Walker, who blew out his knee in a season-ending injury against Carlton in round five, has been adamant he wants to make a contribution to this season. Taylor, he's got great footy instincts ... I know he's talking to the players now," assistant coach and dual premiership captain Mark Bickley said after yesterday's training. Key forward Josh Jenkins at Crows training with assistant coach Mark Bickley. He was fairly successful against Fremantle last year, particularly in the final and in a couple of other games. He'll just pass on some little hints and pieces of advice. He's fantastic; we all know he's a great presence to have around the club and he's in great spirits, which is great to see. How the forward line operates today is pivotal: because of Fremantle's stingy defence, the Crows will need to be brazen to kick a winning score. Bickley tipped it would be a sharp contrast to the free-wheeling game against North Melbourne last weekend, but one the coaching group would embrace. "No doubt, it won't be a shootout this week," Bickley said. It's great for us because one, it gives us a great chance to test our offence, because we think we're doing that reasonably well. And the other thing is it's a great defence for our defence because they play this sort of `sling-shot' offence. Then there is the Sam Jacobs factor. He was out-rucked by Todd Goldstein last week and subbed off late in the game, but Bickley said the coaches were confident he would respond. You're right; he's not as dominant as last year and his numbers probably suggest that as well. It's a tough one. Players go through ebbs and flows with their form. Last week was probably an anomaly for Sam because the prior two weeks were pretty good. We had seen some improvement. His jumping had improved. We expect Sam to bounce back just like any other player who has a bad game and is an experienced player. We expect that we'll see some sort of response this week. We've got great confidence that we'll play well this week. What's the greatest challenge against Fremantle? It is not how to unlock the mystery of how the Dockers play under Ross Lyon, but finding a way to find a weak link. "It's a bit like Brisbane in '01, '02 and '03," Bickley said. Everybody knew what they did. That's probably Ross Lyon's trademark: he's able to put everybody on the same page, he's able to have everyone committing to that.
