If I had to put money down on an outcome, I'd say DLH starts out cautiously, making sure Pac can't hurt him with anything he throws. When he's satisfied of that, he'll realize that he has to win the fight big... 'cause some of us fight fans think he's a coward going after smaller fighters. And since Pacquiao isn't one to back up or fight on the defensive, he would mix it up with Oscar. And somewhere around the 7th to 9th round, Pac would throw a right jab and leave himself open for a left hook from Oscar. And that would be the beginning of his downfall. Oscar could foreseeably KO Pacquiao in the later rounds, to avoid a wimpy decision win.

Needless to say, however... I would be happy to lose a bet like that.
