Roos were lucky, but they usually do find a way to win the close games.
Do you think Tredrea will retire soon? He hasn't seemed to be in any kind of form since 2004, when Port won the Grand Final. And I assume Port will let him go out on his own terms, because of his contributions to the club.
I don't know about the Richmond and West Coast game. West Coast have Kerr back, and Richmond don't have Richardson. I think it could turn out to be a good close game.
