Because Nate didn't fight the real Juan Diaz. Just like Forrest, Diaz was not himself that night. We all know what Forrest did to Mora in the rematch.
I think Guzman was not up for the beat down that was coming his way his supporters had way more confidence in him than he did himself.
I agree, nate is a bad ass fighter. No one deserves it more then him at this point. He worked hard to get there. But I respectfully disagree on the the outcome of the ematch. The real Juan Diaz is a volume puncher, the one that beat the **** out of Katsidis for 12 rounds. I'd like to see Nate handling that kind of Juan Diaz.
getting his ass canned by Peden and losing to Casamayor may have something to do with it #1 is his age 36 is long in tooth for a lower weight guy time is running out or about to.
