1. Steve Waugh hitting a four off the last ball of the day in his last ever test at the SCG to bring up his century. It was building up for so long, there was so much pressure (and doubt) placed upon him, and he just stood there and delivered.
2.[AFL/VFL] Malcolm Blight's kick after the siren to level the scores in the 1976 AFL grand final. The video footage is amazing... the opposition players (all of them) are lined up, jumping up and down and yelling, doing everything to try and put him off, and he simply goes back and drills it.
3. [AFL/VFL] The Wayne Harmes incident in the 1979 Grand Final.
Taken from "abc.net.au":
"Wayne Harmes didn't kick it but he created it, from nothing. In a moment of frenzied genius, as his team clung to a four-point lead, he pursued his own wayward kick out to a forward pocket where no player or boundary umpire stood.
As the ball slid to the boundary line he dived after it and, aqua-planing across the turf, slapped it back in to the goal front.
There was Ken Sheldon to gather and goal. Collingwood fans still say the ball was out of bounds. The best the old replay can do is to confirm that it was close."
4. [AFL/VFL] 1989 Grand Final, Geelong V Hawthorn. During the opening seconds of play, Dermott Brereton was taken out by an opposition player in what was a predetermined attack, issued by the coach. Dermett went down hard, fracturing 2 ribs and suffering from internal bleeding and concussion. In obvious pain and discomfort, he throws up on the ground, and battles off the trainers as they try and remove him from the ground. He literally has to push away the trainers and meds as they try to restrain him. He goes on and plays the whole match and is a key player in Hawthorn's win.
5. There's 100 more AFL/VFL moments I could mention that I've just thought of.... John Coleman, Jack Dyer, Ted Whitten going around the MCG one final time before his passing, etc, etc...
