Cuban judo Olympian Hector Lombard followed the same path as many other prolific grappling to MMA transfers.
Noticing fairly early that he had the physical attributes and technical aptitude to knock people out, he made less and less of an effort to initiate wrestling situations and work his base advantage.
Needless to say, it’s a more difficult proposition for a judoka to constantly have to punch their way into favorable tie-ups and find the positioning for throws than for a wrestler to take leg attacks from space with much less effort.
Fortunately, Lombard did not completely abandon his judo, his fight with wrestler and “American jiu-jitsu” black belt Jake Shields was by far his most clinical display.
