This kind of stuff really should be looked by all the sports science/tactics boffins around the league (and our own supposed gun in this regard- rath).
When you a faced with a 50/50 or worse target kicking inside 50- what's more effective:
A. Trying to hit your target or
B. Forget trying to hit the target- and instead just chaos ball it in their general direction (either with a scrub kick or a torp etc like higgins did).
I reckon the conventional wisdom that you always should try and hit your target is a lower success rate.
Richmond were the masters of it, better to keep the ball in motion and push it up the ground than try to cut through slowly with good disposal. The scary thing about Collingwood this year is that they have speed and cleanliness. They move the ball with Richmond speed but don't turn it over as much.
