i agree with the workrate and the stamina to a certain extent but heres where we disagree. To me Pacquiao fought Rios the pretty close to how he fought Margarito, and i dont remember people saying he had slowed down there. He fought those fights pretty identical to each other and no one complained last time.
Now onto the bigger issue, when you say troubled what are you referring to? was it a close fight? maybe i had it 116-111 so i guess if you consider that close, but do i really think he troubled pac? not really. He had some moments but not enough for me to say wow bradley might be able to pull this off. Are you telling me that you are under the impression that bradley can knock out manny? Or do you think he will outbox him? Because i dont think he is capable of either. Bradley is beginning to get dangerously overhyped for his boxing ability which i have admitted was very good, but some people like i said before are acting like hes the second coming of Willie Pep. He already tried to outbox manny and i didn't work in 98% of boxing fans eyes. And as for him knocking him out……..well lets just say i dont see it happening……...
Pacquiao almost threw 300 more punches against Margarito and generally put it on him to an appreciably greater extent. Margarito was a better fighter than Rios and he pushed Pacquiao harder which partially accounts for Pacquiao's substantially higher workrate against Tony, though. Still, Pacquiao was undoubtedly more offensive and more consistent in his work throughout the round against Margarito. I think a Pacquiao in his prime would likely stop Rios, or at least come much closer than he did. Now, that's not to say Pacquiao did much of anything wrong against Rios, but some, including myself, perhaps predicted him giving Rios, a tailor made opponent for a bounce back fight, a more severe beating. Regardless, he beat Rios easily and that's that.
Pacquiao undoubtedly had trouble sustaining meaningful offense against Bradley, especially in the later rounds when Bradley made a concerted effort to box behind a jab. That's not to say that Bradley had considerable offensive success himself, but limiting a man that many refer to as the greatest offensive fighter since Duran as much as he did is significant, and it certainly constitutes troubling Pacquiao, in my opinion. How much of that had to do with Pacquiao having a bad night, and how much that had to do with Bradley keeping an active jab and moving laterally is open to interpretation, but there is enough evidence in Pacquiao's career to suggest that a fighter who is more content to box Pacquiao as opposed to coming straight at him is likely to have more success lending some credence to the assertion that Bradley certainly did have something to do with an uncharacteristically poor offensive showing by Pacquiao.
As for the scoring of the fight, it wasn't an easy thing to do because there were a lot of close rounds that could be interpreted various ways according to personal judging preferences. I'm not going to get back into in depth scorecards (we've done enough of that on this forum), but I saw it as a close fight, and any scorecard that I think is acceptable would reflect that (roughly 116-112 Pac to 115-113 Bradley). I predict a similarly close, and potentially controversial rematch this weekend.
