If by "dude" you mean "Matt Hughes" then absolutely. Why can't you face the fact that Matt Hughes looked like a red headed stepchild after thirsty thursday? BJ Penn absolutely dominated Hughes for two rounds. He outstruck the hell out of him, made a complete mockery of his takedown attempts, and damned near submitted him. It wasn't until his OWN actions caused him to injure himself that Matt was able to do anything (and not even then...he needed the round to end to turn his luck around).

After Hughes was injured, Hughes STILL couldn't knock him out, despite the fact that he was a friggin punching bag. He was flat footed with his hands down and essentially LETTING Hughes tee off on him. When he had Penn down in the crucifix-esque mount, he STILL couldn't finish the fight....he just "pummeled" him with weak shots until the ref called the fight....BJ most likely could have survived another three or so minutes of that and come out for another round.

Hughes put on a terrible performance, and only won because of a freak injury. His body DID fail under pressure, but that has nothing to do with "durability." That's like calling someone weak for rolling their ankle and it hurting. It's just a freak accident that happens and hurts. And if BJs durability shows anywhere, its the fact that he STILL almost managed to submit Hughes after being injured, and STILL came into the ring for the third round with the injury, and Hughes STILL couldn't knock him out standing and STILL couldn't submit him on the ground. His shots were NOT hurting Penn in any serious way. Penn should have been out cold or tapping at the end of that fight, not ref stoppage. Hughes had NO reason not to conclusively finish that fight against an injured opponent.

So by your reasoning, this fight shows that both fighters were durable and both were unable to finish the fight, making them both great fighters and terrible at the same time.
