It's not. We are one of the fastest teams in the competition.
When we win it's because we play hard, contested football and don't turn it over very much. When we lose it's because we play soft football and turn it over a lot.
We are also less successful against certain setups. The teams that have made us look silly have focussed on taking the corridor away and freeing up men behind the ball better than we've been able to. When we run out of options in the corridor due to pressure we take risks or bomb forward and turn it over (e.g. Carlton game, Melbourne, Freo, Richmond).
I think we'll gradually get better at playing through congestion in the middle but it's going to take a while and there are going to be bad weeks.
