What makes you think that? The last 2 times the sides have met we've flogged them by 10+ goals, that doesn't scream 'good match up' to me, you need to go a bit further back to see when they were competitive with us, so far back it's practically irrelevant.
Things happen.
Who would have picked Essendon to beat Geelong last round.
That's not setting out to take anything away from Collingwood, but I won't be surprised to see them lose another couple before years end.
This one just looks like it could be one of them.
I'll certainly have some money on North, this weekend.
