? about BJ's cardio

BJ's cardio has always been the one weakness people point to in his game. This may sound stupid, but why is this his weakness? For example, early on he was a BJJ world champion. That obviously takes a lot of cardio to achieve that level. His early UFC fights it really didn't come up. When he left the UFC, he went the distance and unanimously won fights against Rodrigo and Renzo Gracie. He went four rounds and defeated Gomi. He went the distance with Machida at heavyweight. Why has it been such a HUGE issue the last couple of years? Is it an age thing? People act like he's finished if it goes past the first round. I know his training has come into question, but it's not like he doesn't train for these fights. He should be able to fight like any other lightweight and not be winded so easily. Any thoughts...

What's your point? Is this grammar class?

When he tried to fight at 170, his cardio sucked. At 155, he looks great.
