I'm sure it will be a tight game. For anyone interested, here is Vince talking about it:

With regard to the GWS game, apparently everyone who played at the MCG in round one lost the following week (cause of hard surface after cricket maybe?). Maybe that's one of the reasons why we lost anyways i'm expecting a nail-biter this week. We play good at Adelaide oval.
