JDS totally underestimated and disrespected Cain's stand-up skills and that's what cost him the fight. He started off well, defending takedown attempts and getting back to his feet quickly when taken down. He thought that the only thing he had to worry about were takedowns. But after that punch landed, it was all over. He wasn't able to recover from it. It was the beginning of the end and I'm surprised he lasted full five rounds. People who are questioning JDS' cardio have never been hit in the gym (or more likely never stepped into the gym at all). It's not cardio, when you get hit in the chin clearly, it takes everything away from you. JDS needs to go back to the drawing board, the same way Caind did after their first encounter, and I believe he's one fight away from the title shot.
