What was wrong with Rolles Gracie?

I don't fight in a cage for a living, so I'm not going to dump TOO hard on Rolles Gracie, but honestly, that performance was just crap. He seemed to gas out after a minute. Did no one tell him it was three five minute rounds? I'm actually thinking he had a huge adrenaline rush when the fight started and had nothing after it wore off. He's a young dude, I hope he improves his cardio, or gets over the ring butterflies, because he could be a force in the heavyweights.
