Has Mayweather "hurt" any of his opponents?

Theres a reason people didnt walk him down like some could with let's say a paulie.

He may not have had amazing power at 147 but he had enough pop to keep people at bay and weary of his counters

He visibly hurt cotto Mosley (who by all accounts had a great chin) maidana with some body work, wobbled dlh a couple times even had manny backing up from a few right hooks that seemed to get his attention.

He sat JMM on his pants, he didnt fall over.

As I said before his power is 135 , every opponent he fougt he could have probably stopped or dropped at 135, why cant ATG 147 fighters walk through him, why do guys like Mosley and Oscar say his power is about the same as Mannys, when you figure that out you will know a lot more about boxing than you do now.

Marquez in his previous fight was a lightweight that he welched on the scales, and still couldn't get the ko.

Mosley and Oscar were over the hill Floyd couldn't get the ko on those guys not even a knockdown.

What all time great ww in their prime did Floyd actually hurt, or knockdown or knockout. Oh I forgot he ko'd a prime Victor Ortiz because he had his hands at his sides. Sharmba Mitchell maybe?
