Also, it has become rare for the top 100m dash men to also long jump, the way Owens in 1936 and Lewis in 1984 won four gold medals by combining the 100m, 200m, 4x100m, with the long jump.
With the rare, storied exceptions of Jesse Owens v. Luz Long in 1936 and Lewis v. Powell in 1991, long jump competitions tend to be anti-climactic and frustrating for audiences. A lot of leaps turns out to be fouls and the standard practice is not even to measure fouls, such as on the legendary 1982 jump that Lewis claimed might have been 30 feet.
A typical anti-climactic performance is Lewis at the 1984 L.A. Olympics. He comes out, jumps 28 feet on his first try, then figures that in the cool damp L.A. night time air, nobody else is going to come within a foot of that and he needs to conserve energy for the rest of his busy schedule. So he packs it in for the night to boos from instant experts who wanted him to pursue Beamon's record (even though Lewis was likely a lot better judge of what he was capable of at the moment than anybody else in the Coliseum).
