The forward handball is clearly drilled into them.
If you watch the brisbane game they actually used it to effect at times. There was some close calls though, but the difference was the receiver was more often moving, and moving at the correct angle, and there was little opposition pressure. We have seen how it falls down when the opposition put pressure on them, like last night and the footscray game..
as i said, these things are either being drilled into them, or the coaches cannot recognise and rectify them. Either way it is the coaches who shoulder the blame for them.
