2012 was a much more successful year for Atley. He played every possible game, and was noted as one of the competition's most improved player. The catalyst of this change of form was a move to the backline, where he used his explosive pace and blistering speed to accelerate out of defence on numerous occasions to turn defence into attack. His kicking improved out of sight, and this was recognised with a fifth placing in the Syd Barker Medal.
He is the brother of Joe Atley, who plays for the Essendon Football Club's VFL side after being delisted by the Port Adelaide Football Club.
Atley was delisted by North in October 2021 after 234 games for the club.[5]
