Here are Edwards's 18.43/18.16/18.29 jumps.
On the 18.43, he just looks so strong on the run-up; the announcers say he'd been really working on his power that season. And he transitions through the hop and the skip with incredible fluidity as if he is hardly losing velocity, and incredible control. He does not extend way out and get everything possible out of the jump at the end in any of these triples, not in the way that Harrison did in 1996. And indeed, at Gothenburg, where he had the two WR's, he says later (see wiki) that he had more in the tank, that he could have gone as far as it took to win and didn't need to jump farther.
