By Jason Kim: After watching the bout between Floyd Mayweather Jr. (41-0, 25 KO’s) and Shane Mosley last weekend, WBO welterweight champion Manny Pacquiao (51-3-2, 38 KO’s) thinks he would have finished off Mayweather had he hurt him in the 2nd round like Mosley did in their fight. In an article by Michael Marley at Examiner.com, Pacquiao said “I saw that [referring to the 2nd round of the Mayweather-Mosley fight], I did. If I can hit Mayweather like that, I will finish him off.” Mayweather was hurt on two separate occasions by hard right hands from Mosley and needed to grab Mosley to keep him from punching in order to get out of the round.

Mayweather had the lucky benefit that Mosley appeared to gas out after only throwing a small handful of punches in the round. Mosley stayed tired looking for the remainder of the fight and fought like a 38-year-old. Say what you want about Pacquiao being technically flawed, he has excellent stamina and would likely keep the pressure on Mayweather with a high volume attack for as long as the fight lasts.

It would be a much different fight compared to the Mosley bout, because Pacquiao wouldn’t stop punching like Mosley did after the 2nd round. Pacquiao would be on top of Mayweather all night, throwing a lot of punches and forcing Mayweather to fight back or else get taken apart. Pacquiao says “I would continue the attack in a way that Mosley did not. I will attack until Mayweather is gone.” That would be problems for Mayweather unless he was able to find an answer to Pacquiao’s power and pressure attack.

I doubt that Mayweather could win the fight by running for 12 rounds. Pacquiao would have too many chances of catching Mayweather in each round and would be constantly testing Floyd’s chin. The punch punches that Mosley landed against Mayweather in the 2nd round would likely be repeated in every round over and over again. Could Mayweather stand up to the shots without getting wobbled repeatedly? It’s hard to say. Mayweather hasn’t faced a relentless puncher like Pacquiao before. This would be the first time. This isn’t a slow and wide open Ricky Hatton that Mayweather would be facing. Pacquiao is about as fast as Mayweather, and probably a little more powerful.

Pacquiao seems less willing to agree to the Olympic style blood testing that Mayweather is insisting on, saying “My message to Mayweather, to the world, is simple: I am not the lawmaker when it comes to the rules and regulations of any boxing commission. That is not my job or my duty. Neither is it Mayweather’s unless he forms his own personal commission. I will comply fully with whatever drug test, blood or urine, rules are specified by the commission of the place where this fight is arranged.” If Mayweather wants the blood testing done, it will have to be something that the commission mandates.
