Edmen's weakness is Spoiler NOT Stand-up striking - technically, Edmen was decent. He was getting the better of the exchanges in round 1 against Brunson. NOT In the clinch, he did ok. Takedown defense was a bit below average (Brunson's takedown attempts weren't very strong, but Edmen couldn't defend them). But this wasn't a glaring weakness that cost him the fight. What is wrong with this picture? Edmen has the same fundamental (nontechnical) weakness that Rousey and many martial artists in the Judo discipline have. Do you know what it is? Edit: everyone who said cardio is correct! Some examples of top Judo fighters with average to below average cardio: 1. Dong Hyun Kim (aka "DHK") 2. Hector Lombard 3. Karo Parisyan 4. Ronda Rousey 5. Satoshi Ishii (Judo gold medalist; fights in Bellator, PFL, Rizin) 6. Sokoudjou 7. Yoshihiro Akiyama (aka "Sexyama") Question: Do you agree that one of the fundamental weaknesses of Judo fighters is cardio? If so, why do Judo fighters often have problems with cardio, while many wrestlers do not?
