In R2 2019 Collingwood took 159 uncontested marks against us. We have always been vulnerable once a team takes clean possession, we gave Sydney far too much of it yesterday via poor turnovers and tackling.Very occasionally a team can do it and usually Richmond would be able to quickly stop a side after 1 or 2 quick kicks by working the mark and stop the flow of the ball. That looks much harder to stop this season
