I think this is what makes it difficult to assess the forward and defensive line.
I would say that our current bookends are pretty good. We have a forward line than has done well despite the lack of high quality supply, and when that supply is good i.e. Port and St Kilda games, we tend to whip the opposition. Similarly, our defense has let through a few goals, but when your opposition is getting good supply i.e. yesterday, no defense is going to beat that.
