Its very very clear we lost because we were thrashed by contested marking .
We average 11.6 contested marks per game. we managed 8, but we allowed Sydney 26 when they average half that. Even Hooker only averages 2.6 contested mars per game and he is the equal best contested mark in the comp in 2017.
So, given that a lot of the contested mark difference ( 18) were inside F50 for the Swans, it accounts for the goals kicked against us.
Why? Without going back over the painful 2nd quarter replay, it appeared our defenders were blocked, failed to make the contest and an extra Sydney player often dropped into the hole and marked.
In this respect, our defenders were comprehensively outplayed by Sydney forwards body positioning.
Add in another couple of Buddy goals from poorly defended leads.
