All these people claiming that Cain will beat Werdum in the rematch, what are you on about?? Have you not watched many of the similar rematches in mma history? Of course Cain has a chance, but based on how the first fight looked, Werdums/Cains improvement rate and what history tells us, Werdum is very likely to win. Barao vs TJ 1/2 No one expected TJ to win first fight, but he did convincingly. Second fight people were still making excuses why Barao wasn't good in the first fight, he got caught early and couldn't recover and this and that. Second fight was an even easier win for TJ. Cain vd JDS 2/3 It's fair to say Cain got cough in the first fight. Of course a valid JDS win, but it was so short that it didn't say much about the competitiveness of these two. Second fight Cain kicked JDS ass big time for a full fight and won a decision. How did the second fight go? Even worse for JDS. BJ vs GSP 1/2 GSP won the first fight by decision, close but decisive win. Second fight was a beatdown of the sort that BJs corner threw in the towel. Not as obvious, but still proving my point... Machida vs Shogun 1/2 Most of us agree that Shogun handily won the first fight, despite what the judges said. Second fight it didn't take long for shogun to (again) show he had Machidas number. You might argue that there are some exceptions to this, like GSP vs Serra or GSP vs Hughes. The first is a case of GSP getting cought and the second is a case of their careers were going in opposite directions at the time. Hughes declining and GSP improving between the fights. None of this can be said fr Cain vs Werdum.
