Adelaide star Taylor Walker has spoken out against free agency in the belief the recently relaxed player movement rules will ultimately harm the competition and widen the gap between the rich and poor clubs.

In an exclusive interview with Fairfax Media in the lead-up to the Crows' crucial clash with Collingwood, Walker said he resented the increasing Americanisation of Australian rules football at the elite level and feared the AFL too often copied the US in formulating changes surrounding the game.

Walker, who returns to the MCG for only the second time since last year's season-ending knee injury against Carlton, also pointed to fixture time slots and the tightening of concussion rules as key indicators that the AFL was too US-centric in shaping the game.

"I'm not a big fan of free agency," the 24-year-old spearhead said. "I think it takes a lot of loyalty out of the game and now they're talking about freeing players up even more. The age they are looking at is too young. I just don't see why we have to follow American sport in so many things we do.
