duncan never quite made it to elite all australian midfielder level? Why? Cos as good as he was he was always a bit soft when it came to the contest. Not exactly the way a captain played. Been caught shirking a few aerial contests this year too. Great player. but he had one thing that stopped him from reaching the next level and its the thing that made players follow them into battle.
Because there's far fewer positions in the AA side available each year for outside mids/wingers. Traditionally there's been 0-2 of those types of players selected. On-ballers on the other hand have ~8-9 spots available to them, and more often than not they're crammed into the side in place of Duncan-type players.
It's the only reason that guys like Isaac Smith and Mitch Duncan don't have an AA jacket between, despite a decade of being among the league elite in their role.
