Port are playing a seriously good brand of football. This isn't like Brisbane beating up on Melbourne yesterday playing less shit than them, this is a good side confidently dismantling terrible teams and showing the absolute desire to win that their more fancied opponents are missing.
With Tex out of the picture for a long while, Carlton or West Coast (in that order) in for Richmond is the only change I'm expecting from the current top 8.
I think North will make it. Their draw gets much easier from now on.
