I'm gunna put money on JMM to pull off the upset. I think Floyd may have looked past this, underestimated JMM's skills and I can see JMM being smart enough to work his way inside and pound the body to exploit te previous rib injury. It's just a feeling, but I think it's worth a bet as despite the weight, Marquez is a live underdog and I'm stunned so many people have written him off.
