Maybe it's not our physical size actually. I''ve been thinking that, but I think other forwards in other teams make themselves seem bigger by just being more aggressive. It kind of makes the opposition forget you're smaller than you make yourself out to be. We aren't being helped with soft players like Hunt.
When you are fatigued from backpedaling as you have lost the wrestle in the ruck and can barely get onside you tend to lack aggression as well. I do agree they need to fire up a bit for sure but you have to look at the cause not the symptoms.
