Adelaide Crows forward line starting to click without Taylor Walker, says captain Nathan van Berlo Adelaide captain Nathan van Berlo high-fives Josh Jenkins after a Jenkins goal against St Kilda. ADELAIDE has finally found its new Taylor Walker-less forward system - and Crows captain Nathan van Berlo warns it will only get better. After months of debate on how the Crows would restructure without key forward Kurt Tippett after he defected to Sydney, Adelaide has been forced into a makeshift Josh Jenkins-Shaun McKernan-Tom Lynch combination with the season-ending knee injury to Walker. And on the evidence of productivity in the 40-point win against St Kilda at AAMI Stadium on Sunday, this trio has promise, particularly with the threat posed by Jenkins in the goalsquare. "That (multiple-option attack) is one we've really tried to work at - and not just since Taylor has gone," said van Berlo today as Adelaide hopes to move into the positive on the win-loss count for the first time this season by beating North Melbourne at Etihad Stadium on Sunday. We've spoken about it a lot. Tom and Josh are our key forwards with Shaun McKernan. They have been playing their role really well for us. The chemistry between (the three) is only going to get better as they play together more. Jenkins has pulled up well after hyper-extending his right knee early in the clash against the Saints.
