junior twarted all 4 of cains first 4 takedowns when he was fresh and then he gassed and voila
That's not what happened at all, man. Cain strategy clearly found JDS's face first, then he got dazzled by the following hits. JDS went through 5 rounds of punishment against Cain Finisher Velasquez. How come he doesn't have high level cardio for that accomplishment alone?
As for Overeen, not taking his juice will certainly decrease his power, but that could actually improve his cardio.
