Could be an "out of the box" pick. Would be hit and miss but if he turned out like Roughie it would be a win.
I think throughout the course of his career, Walker has proven a valuable backup at both Geelong and Brisbane. He has played the occasional game where he has looked like a superstar, but they are few and far between. Typically, he is good for a cameo here or there, or as depth backup.
I would say Roughead is much better player, and I don't think we'd get the same level of output from Walker as him.
I'd be looking to Walker for pure depth. I'm not keen on bringing players in just to be depth...but when the cabinet is empty for KPPs then I think we really need someone. Walker would at least be a really solid call-up when the inevitable happens that both Reid and Darcy Moore are injured.
I don't think he did much wrong for Brisbane, and was a really solid contributor in their NEAFL premiership. He is just behind the likes of Hipwood, McStay, McInerney, Harris Andrews and Darcy Gardiner. Plus the Lions have a stockpile of your KPPs just waiting for opportunity.
