Mosley by late round TKO. Mosley is still more of a fighter than Quintana. Although not in his prime he is still very very good. Too strong for PW. Also too quick. I hope this fight happens.
Williams by stoppage ... at this point of Sugar Shane's career, he's not good enough to hang with a young guy like Williams ... I think the pace that Williams fights would be too much and would prove that Sugar Shane is not only past his prime but too old to hand in there with the young bucks.
