Juan's best days are gone.He should enjoy his new career and study to pass the bar exam.He still has a long way to go before he is a lawyer.
After Marquez TKO he wasn't the same fighter anymore, he was unwilling to trade shots which made his career to what it was, and tried to become a boxer instead of a boxer puncher it didn't work out for him... After Marquez TKO he goes on to to get a gift win over paulie, then a loss against paulie, and a UD loss to Marquez in which he was happy to end the fight standing up on his both feet instead of the ground, which is why part was not a FOTY because Juan wanted nothing to do with Marquez's big shots and he boxed all night and avoided trading. He is done.
I've always liked Diaz and his fan friendly style. If he still has the passion to fight, I would welcome his return to the ring.
