Everyone and their mom is picking Marquez (I am too), but if youv'e seen Juan training (I live in Houston) then you would have to view the line as inflated. Ronnie Shields has Juan throwing combinations and then sliding out. Diaz has faster hands than Marquez and I can see Diaz once again winning most of the early rounds. They've also been working on using the jab alot more (Diaz has a better jab in my opinion) and "fighting in spurts" so as to not tire or be as susceptible to uppercuts. Speaking on uppercuts, they're also working on defending this punch and countering it with combos. I've heard some say that Diaz isn't capable of changing his style and that is complete bullshit to me. Diaz will never be light on his feet, but at 37 yrs old, Marquez isn't either. I'll concede that Paulie made Diaz look bad, but Paulie's got amazingly quick feet and a long fast jab. Paulie's style is Diaz' kryptonite. Diaz' bad showings is why the line is more inflated than it should be.
I'm picking Marquez by a very uncomfortable dec. Marquez always has a mid rounds surge (not counting Mayweather fight) and I believe Marquez can hurt Diaz with one punch but not the other way around. I hate to dissapoint but I guarantee this fight will be more tactical than the first. I'll probably end up pounding the over and/or the Diaz +15.5 points prop.
