Not any of those guys you mentioned would have beaten him. PBF would go undefeated fighting MAB's resume EM's and Pac's.
26 year old Pacquiao had by far the best combo of speed, power and stamina of the era. The most physically gifted fighter of his generation. Later into his career those attributes eroded. Morales is still on God mode 10 years later.
No he didn't RJJ had more and RJJ's win over Hopkins ****s on Pac's whole career.:deal RJJ is the most physically gifted fighter in history with Ali being a close second.
RJJ had less p4p power than Manny And less stamina and could not sustain the same workrate. RJJ had more speed. Most physically gifted fighter ever is Robinson.
Roy Jones was far better than Robinson from what i'm watching when you compare attributes like defense, counter, ring iq, distance control, etc.
Babality said that Floyd fought garbage and past-prime guys at 130. The reality is that nobody was on his level at that weight.
Nelson would be interesting but then again he lost badly against another defensive master in Whitaker (at 135 mind you) so I'm not sure. I think Chavez at his best at 130 would have a shot. He didn't stay at 130 long but the Fenech who fought Nelson the first time brought relentless pressure and was strong as an ox. But Floyd was fantastic at 130, no doubt. I reckon someone, somewhere had what if takes to beat him (there is usually someone out there who has your number) but I don't know who it is.
Floyd doesn't like pressure. JLC beats Mayweather. If Mayweather's ribs were busted up after the JLC fight, imagine what a legndery fighter like Julio Cesar Chavez would do? The great JCC would destroy Mayweather.
Arguello is my #2 Super-Featherweight ever but Floyd seems like a bad stylistic match for him. He did have excellent timing, murderous body-shots and a lethal right-hand, so he could theoretically time Floyd but I just cant see it. I think Floyd's movement stymies AA and he wins a decision. JCC is interesting but I think it would be a better fight at 135, where Chavez put everything together and seemed more well-rounded. He was more patient and seemed on top of his game at Lightweight. From what I've read, Saddler would be a very tough match-up but, truth be told, I'd favour Floyd over anyone at 130lbs. I can find guys I'd favour over him at 135 and 147 (154 too obviously) but I think he matches up well against anyone at 130 and, to a slightly lesser extent, 140lbs.
