For want of a better term "defensive mechanisms" are where we need to improve the most. We leak way too many goals, and that isn't always the fault of the back 6. Hence the appointment of Ross Smith.
We improved forward of centre in that we no longer rely on Jack as our only avenue to goal. Hopefully that continues to develop and improve with the natural progression of Vickery and Griffiths, as well as Nahas and the midfield goal kickers.
We weren't bad in clearances and contested ball, but obviously we have to improve there as well.
We also need improvement in creating a lot more uncontested ball, so bringing the ball out of the back half without risking turnovers is where we get smashed by the good sides.
In terms of personnel, obviously we lack of a big-bodied ruckman with some real mongrel, and we need more pace and class in the midfield to really pressure other sides around the footy and use the ball when we turn it over our way.
