Yeah, if judges continue to give him credit for punches thrown instead of punches landed he will win and the likes of Julie Ledderman do the judging, then yes, easy decision win for PW. Well, except for the fact he will be slumped somewhere on the canvas and unable to accept his 'victory'.
Espino is a full fledged middleweight with an honest middleweight chin. Sergio Martinez is an average sized JMW with a 50% KO ratio against a lot of suspect opposition. Do the math: Williams would not get up from that uppercut that dropped Espino the first time.
Don't be so sure. It will be a high workrate boxing match with both men trading so much, they'll be saying FOTY after 3 rounds. A few rounds later, Paul gets KOed...maybe brutally. Thats what happens in Pavlik fights. Wiliams isn't a real MW & doesn't bang very hard. Kelly will catch him & that will be it.
