I remember after Floyd beat Marquez people were starting to retract their belief that Manny would just run rampant on Floyd if they fought. Then Manny faced COtto and Clottey and that instilled the same enthusiasm in his fans until Floyd beat up Mosley whom many felt both Manny and Floyd were ducking. THen Manny faced the guy who Floyd has been given the most flack for not fighting in Antonio Margarito, and Manny has looked great, but does anyone think that Floyd wouldn't have pitched an absolute shut out against a guy as ordinary in skill as Antonio?
To me Manny has been hand fed the same makeup of opponent since moving up in weight. They have given him guys who allow Manny to make the most of his style and his speed. Diaz, ODLH(weight-drained), Hatton, Cotto, CLottey, and Margarito are all guys who come forward, and with the exception of a younger Oscar and Clottey they are all easy to hit. I will be the first to give Manny credit for looking absolutely amazing and being so tireless in training so that he could give the kind of performances he did, but these were all guys right there in front of him, and when anyone stands just right there in front of Manny they are going to lose. The one guy actually of all of them that was IMO the most impressive win for Manny was against Hatton, because he actually has fast footwork and he uses angles coming in, but he couldn't overcome those huge mistakes that he makes against southpaws in particular, and Manny was the absolutely antithesis of the type of guy hatton could get away with those mistakes again. But these guys made Manny look like a non-stop punching machine with power, counter punching ability, a great chin, and great footwork, but I would like to disagree to a certain extent this belief. I think it's curious that Manny was able to throw more punches than he ever did earlier in his career against guys so much bigger than him, but then I looked a little more closely. Manny's angles, combinations all came when his opponents were rooted to the ground. When Manny was dancing around these guys, they were simply following him, and standing their ground. Manny was basically given a punching bag that followed him around, and nobody looks faster or better on a heavybag than Manny Pacquiao. Go back and watch Pacquiao-marquez II and see Marquez either beat Manny to the punch with his right hand or take a step back to get just out of range of Manny's attack. This is from a guy who isn't even a particularly good defensive fighter, but he had a antidote to Manny's offense that looked so relentless against Morales two fights earlier, and watch Barrera go against Manny the second time. Or Jorge Solis, watch how that movement took away Manny's punch output.
Now I think Floyd would mostly come forward against Manny, but I think it would be in a similar way he did against Judah. I don't think he would be particularly lead leg heavy, and he would stay light on his feet so if Manny tried to come in with a combination that he could move away quickly and wait for Manny to be off balance before coming in, but I think he would also use similar tactics as Marquez and beat Manny to the punch because Manny kind of drops his hands before he ever throws punches in bunches, and a guy like Floyd could tee off on that. Furthermore watch how good offensively Mosley looked against Margarito, he looked amazingly fast, well conditioned, etc, etc. Even at the advanced stage of his career, but Floyd negated him, not because he was physically faster than Mosley as much as he was so much sharper in the ring. Now I saw Manny look great throwing punches at Margarito, Cotto, CLottey, etc, but I also saw Manny getting hit by punches on the outside, he is an amazing combination puncher, but he isn't the greatest boxer on the outside, and I think all it take is movement to dissipate Manny's offensive combinations, and then you have Manny at his weakest element and that's trying to box like Mayweather, Leonard, RJJ, Hopkins do. Take away his output and he is like any other fast fighter that isn't "different". What makes Manny different is his speed and power combined with his stamina. Floyd arguably has better stamina and vastly superior technique with the same speed. We've seen Manny exploited in the fact that he lacks true technique and I don't think his recent fights have forced him to change that. In fact I think his sparring in preparation for this fight prove that if Manny isn't at his fastest that he has a hard time with relatively ordinary fighters. Whereas a guy with really great technique can adapt way easier to variables in the ring.
