Oh I realize that, but he does some of the same thing against Judah. This was mainly how to deal with the jab not pacquiaos whole plan for the fight. Corely did decent work against mayweather, even buzzed him on a few occasions so I cant agree that he dominated him.
The dilemma in this situation is to how to get pac to use floyds jab to create offensive opportunities for pac and his short arms. Pac very susceptible to the jab, as his head movement a lot of times is a preemptive fluff, because he doesn't actively slip a lot of jabs with head movement. He stays out of range, flashes some head movement and then engages from angles behind the double jab anyway. His previous linear attacks had him eating a lot of jabs coming in and getting turned himself (like morales did to him those years ago). Freddie then added more attack angles and footwork to his game. Neither guy is the same fighter but there are certain traits and habits fighters come up with and will revert to if they are not broken early in their careers.
For pac, most people ruled out the KO because the feel Mayweather wont engage him, so pacs going to have to stockpile points early. Without standing in front of Mayweather, because I believe mayweathers jab will still find manny at some of the angles he uses. So rather than circling away from a power hand which is probably not going to be used aggressively, you turn him so he has to punch across his own body. Turn him and catch him with as many shots to his flank as hes shuffling away from you. (Just make sure you dont hit the kidneys--or floyd will embellish and bayless will get on you) . The in the second stage of the fight, mayweather will adapt and you'll have to find other offense. If hes working out of the shell you have other offensive opportunities as a southpaw.
5 years ago I had Mayweather winning this fight. Now i have mayweather winning this fight. It came down to a fundamental difference between the two fighters. Mayweather changes on the fly and pacquiao wont. He has to go back to the corner and confer with freddie. Pac cannot win this fight with just one style, static, offensive secret, unless he lands THE SHOT that ends it. But mayweathers ring IQ will give him the opportunity to change up first, steal points, and wind rounds while pacs trying to figure out why what hes doing is not working. Pac just cant afford mayweather time to think.
