Could go either way, I'm not betting on it but I won't be surprised if JMM comes out victorious via UD or TKO. Marquez's punching power and chin is very underrated IMO for the fact that he wasnt stopped ever in his career and all of his knockdowns where FLASH knockdowns and he was able to recuperate very quickly. If PAC was less than perfect condition and less defensive minded the last time he could've been kayoed IMO.
Marquez superior CONDITIONING edge will make him victorious in this one.
