I think this fight will go to RJJ. He has all the advantage. Trinidad is a great fighter but he will have problem with his power punch as he will be going up in weight. Sometimes, when a boxer goes up in weight, his knock out effectiveness lessens.Besides, there are doubts as to his knock out power. I just don't know if the rumor is true. I have seen some of Trinidad's fights before and I consider him as one of boxing greats.
