Not sure this one has been done. I think Jackson KO's him in no more than 6 rounds, while slightly behind on the cards.
Martinez's chances are extremely grim here. For all his talent, he was never particularly hard to hit, and didn't have the sturdiest chin. Jackson inside of 5.
Same as above, Jackson in the mid rounds. Sergio made just way too many defensive mistakes for one of the hardest hitters ever in Jackson, whom also had underrated skills himself. Sergio has a better chance at 160, where Jackson already had some serious eye issues, but I still make Martinez the underdog.
