LAS VEGAS -- After nearly being shut out over the course of Saturday night's unanimous decision loss to eight-division titlist Manny Pacquiao in defense of Pacquiao's WBO welterweight belt, Shane Mosley called Pacquiao, "The pound-for-pound king," and, the "Tougher fighter" between him and six-time titlist Floyd Mayweather.

Mosley (46-7-1, 39 knockouts) was dropped by Pacquiao (53-3-2, 38 KOs) in the third round, this, after having staggered Mayweather (41-0, 25 KOs) during a unanimous decision loss on May 1 of 2010.

"A fight [between Pacquiao and Mayweather] would be interesting, but Manny definitely has the good punching power. I wouldn't say that he's physically stronger, but he definitely has more punching power. They're different types of punches that I haven't felt from anybody else," said Mosley, who was dropped twice during one of his two losses to the late Vernon Forrest.

"Floyd Mayweather is definitely the more technical and defensive but very skilled fighter. It would probably be interesting if they both fought to see exactly what would happen," said Mosley. "Mayweather has great defense and Manny has great speed. It's going to be a great strategy to see which one would work the best."

Where Mayweather's elusiveness allowed him to defeat Mosley, the losing fighter said that this time, it was Pacquiao's power that prevented him from asserting himself.

"I'm not sure if there weren't openings that I couldn't pull the trigger on, but there were shots that I couldn't see. I've been knocked down by Vernon Forrest, so that was a strong knockout punch. But this second time, that couldn't compete with Manny Pacquiao," said Mosley.

"I was pretty hurt. I was pretty stunned. It surprised me, because I didn't think that it was a big shot when he threw it. But Manny Pacquiao was very strong," said Mosley of Pacquiao's left hand that floored him. "That was a great shot, and I definitely felt it and went down. And sometimes, he was setting traps. Manny, like I said, his punching power is a little different. You never know what could happen."
