The AFL's general counsel, Andrew Dillon, and his team are leading a review into how the debut of live pick trading worked, and whether such tactics should be blocked in the future.
Sydney traded a second-round selection to West Coast so they didn't have to use it on Blakey when a bid came at pick 10. The Swans then traded back into the second round shortly afterwards.
"It was clearly legal and that's what clever industrious clubs do, they look at the rules and they take advantage of them if there's stuff possible," AFL chief executive Gillon McLachlan said.
"Whether that's available next year, Andrew Dillon and his team will review."
