If Bowden has another consistent year next year he could conceivably get it. I'd be happy for Johnson to have it for the next two or three years though. By that stage we should know about the Deledios, Tamblings, Myers and where they fit into the leadership picture.
Cogs doesn't seem a leader to me. He is strong, hard at it, courageous, and gives a good example to the others about how to attack the footy, but he isn't vociferous enough and doesn't have a commanding presence. Also he doesn't seem to be the most tactically astute. Still, we could do worse.
