By Dave Lahr: After watching Floyd Mayweather Jr. and World Boxing Organization welterweight champion Manny Pacquiao’s last fights, I’ve come to the conclusion that Mayweather would have made easy work of the Filipino star had they fought. For that reason, I think it’s fortunate for Pacquiao that he stubbornly resisted meeting Mayweather’s demands for the blood testing for performance enhancing drugs.

If they had fought, there would have been an excellent chance that Mayweather would have done to Pacquiao the same thing that he did to Juan Manuel Marquez, a fighter who Mayweather totally dominated by a one-sided 12 round decision in September. I see Mayweather beating Pacquiao 10 rounds to 2, with the two rounds given being a case of mercy on the judges’ part. Pacquiao would be too shorter and too much of a plodder to beat a fighter like Mayweather.

Pacquiao has beaten three good opponents – Oscar De La Hoya, Ricky Hatton and Miguel Cotto – in his last three fights, but each one of those fighters were deeply flawed and there for the taking. De La Hoya was old, weight drained and more or less on his last leg at 36, winning as much as he was losing at the end of his career. Hatton was simply a fighter who had been reeling since being stopped by Mayweather in 2007, and whose yo-yo dieting seemed to be catching up to him.

Cotto hadn’t looked like the same fighter he once was since being stopped by Antonio Margarito in July 2008. Each one of these fighters were famous, there’s no doubt, but each of them appeared to be on the decline at the time they stepped foot in the ring with Pacquiao. Cotto was still fighting well, but he looked poor for the most part in his life and death battle with Joshua Clottey last year. Clottey’s a good fighter, but Cotto looked like was about to fold late in that fight.

Mayweather looked sensational against Marquez, moving well and opening up on Marquez with hard right hands. Mayweather doesn’t get much credit for having any power, but I think the right hands he landed in the Marquez fight would have stopped a lot of fighters. Mayweather really dominated Marquez with his right hands and short left hooks. It wasn’t even slightly close. Pacquiao almost lost his fight with Marquez in 2008, winning by a 12 round split decision that many boxing fans question. Just looking at how easily Mayweather handled Marquez, and then comparing it to how badly Pacquiao struggled against Marquez, I can’t help but think that Pacquiao would lose and lose badly to Mayweather.

Mayweather would likely get hit more than he usually does in his fights if he were to fight Pacquiao, but I think he’d still totally dominate Pacquiao and make it look effortless. This fight would come down to whoever is the better boxer. I’m sorry, but I just don’t see Pacquiao out-boxing Mayweather. That isn’t going to happen. Pacquiao is more of a slugger, and not someone that is great at winning round after round like Mayweather. Mayweather would dominate each round, and this wouldn’t be close. Mayweather can’t be beaten on points. The only way to beat him is by knockout, and I think Pacquiao would too small and not powerful enough to take Mayweather out.
