I have to disagree with you there on one instance about Robbie Flower's kicking for goal from a set shot in a real pressure situation.
As a Footscray supporter I vividly recall the Round 3 clash of 1981 at Footscray.
Robert Flower taking a strong mark(it could nearly have been described as a screamer) deep in time on with Melbourne trailing by 5 points. He was around 35 metres out kicking to the Scoreboard / Geelong Road End (that's the right hand end as you notice on television) and he put it through.
Soon after the siren went with Melbourne winning by a point.
So I don't know about other games where he may hot have been as steady with pressure kicks from a set shot, but this day at the Western Oval he certainly was. As an 11 year old going on 12, back then in 1981, I can still recall it very clearly.
