Adelaide Crows ready for versatile Port Adelaide forward line Dangerous Power small forward Jake Neade, left, celebrates a goal with Matthew Broadbent and Cameron O'Shea. ADELAIDE has identified Port's versatility in attack as one of its chief concerns for Sunday's Showdown - but the Crows are confident they have answers for any combination the Power deploys. There is a sense of pace to go with dependable leading goalkicker Jay Schulz, Justin Westhoff has been in barnstorming form after being given more licence to roam - and there's zip from a couple of newcomers. But defender Andy Otten said the Crows had studied the Power's attack closely to prevent being surprised by the new-look Power. "They've been pretty impressive so far," Otten said. I think the whole AFL world's been pretty impressed with the way they've gone about it and we're the same. They've played Melbourne and GWS and have really flexed their muscles against those two sides. They've got a new coach and they're all up and about. We've watched their tapes and we know we can beat them if we play to our strength. They've got a lot of flexibility in their for-ward line now. They brought in (Jake) Neade, who's lightning quick; (Kane) Mitchell who's got a bit of pace when he came on as a sub. Then you've got (Justin) Westhoff, who I think took 15 marks and (Jay) Schulz who is always in form. They've got a lot of match-ups for us but I think we match up pretty well with (Daniel) Talia, (Ben) Rutten and Luke Brown, who is just as quick (as the Port players), I reckon. So I think we match up pretty well. And Otten warned that Adelaide could have a surprise card of its own. Sam Kerridge, who was named in the extended squad, has impressed at West Lakes. And he has the engine to cause headaches if he is named in the 22. "He's probably one of our fittest players, just behind van Berlo, and he can run all day," Otten said. He's a massive kid for 19 years old. They can do whatever they want; we just focus on our side, really. The only times we play them are in the Showdowns, twice a year, so that's the only times we concentrate on them.
