Ahead of Carlton's huge game against Collingwood this weekend, V/AFL coaching legend David Parkin joined Gerard to re-live the Blues' comeback win against the Magpies in the 1981 grand final, and to talk about the essence of the rivalry. He also explained why he thinks Carlton are still four-to-five players short of experiencing real success, discussed when he swapped positions with Robert Walls, and weighed in on the choices Alastair Clarkson has in front of him.
