Jerker Jenkin for me....particularly that day when Jezza was standing the mark, and the botched drop-kick hit him fair in the baby-makers.
It was just too low percentage a kick, beautiful when it came off, horrible when it didn't, and you were restricted to only trying it on dry tracks, so there's about 12 rounds of the season gone. We see the great exponents like Barrot, Tully, Price, Davis in the finals on the MCG but not at Brunswick Street or Western Oval in the mud. Shitful drainage in those days.
The Merretts' great-uncle Thorold was a great exponent of the stab-kick which was just a shortened, faster version of the drop-kick.
I do remember another Number 4's drop kicks as massive, in Lindsay McGie whose career was shortened by him being sent to Vietnam, along with another 4 Essendon players. Only two others, John Scarlett and Wayne Closter, both from Geelong, actually went to Vietnam after bering conscripted.
