By Chris Williams: WBO welterweight champion Manny Pacquiao took some heat from his trainer Freddie Roach for his frequent touching off gloves with 39-year-old Shane Mosley after every round of their fight last May where it seemed more like a friendly sparring match than a title fight between champion and challenger.

Likewise, Pacquiao seemed to be buddy-buddy with Antonio Margarito and Joshua Clottey before, during and after his fights with them. Pacquiao now reportedly is looking to toughen his stance towards his next opponent Juan Manuel Marquez in their fight on November 12th in Las Vegas, Nevada. Pacquiao intends on making sure he gets the killer instinct for this fight so that he doesn’t end up getting out-boxed by Marquez like he did in the first two fights with him.

“If my opponent is nice and friendly to me then that carries over into the fight, Pacquiao said to Iol.com. “Then I am not eager to finish the fight. Before Marquez was saying bad things about me. Now he is saying good things about me. I am thinking how to shut this guys mouth.”

What does Pacquiao expect? Of course, Marquez is going to say bad things about him to try and get the fight, but once he’s got the big cash fight, he doesn’t have to be mean anymore. He gets the big payday whether he’s mean or nice, and Marquez is typically a quiet guy that doesn’t say whole let before his fights. He speaks in the ring with his fists.

Pacquiao of all people should know that by now considering he’s faced him twice already. But it sounds like Pacquiao is making excuses for his inability to close the show against Clottey, Margarito and Mosley. I don’t think it would have mattered what Pacquiao did against those guys, the fact of the matter is they were too big, too skilled and too sturdy of chin for Pacquiao to run over.

The guys that Pacquiao has knocked out since he moved up in weight are small guys like Miguel Cotto and Ricky Hatton, or old guys like Oscar De La Hoya. Cotto and Hatton are tiny 5’7″ fighters and really aren’t what I considered to be legitimate welterweights in body size. Cotto may be fighting at junior middleweight now, but look at who he’s being matched against: Yuri Foreman and Ricardo Mayorga.

Those aren’t dangerous fighters and Cotto was able to beat them despite his lack of size. Pacquiao just doesn’t have the size to beat good welterweights of normal size for the weight class. It’s just not going to happen. He’s not going to knock out Marquez either, so his trainer Freddie Roach needs to shut his yap about that happening because Pacquiao won’t be knockout anyone in that fight. Marquez may not be a big fighter, but he knows how to fight. If Pacquiao fights with anger against him by not fighting smart, he’s going to look as silly as he did in his previous two fights with Marquez.
