If pacquiao takes on a light puncher like Foreman, he will probably be able to win a decision. If he were to take on Sergio Martinez, he will get knocked out. He shouldn't be fighting above welter. There's no point in him moving up when there are so many challenges at welter. I would like to see him fight Shane Mosely after mosley destroys Berto in their upcoming mismatch. I would pick Mosley by KO in that one as well.
