What would Pacquiao's legacy have been if he had retired after the Margarito fight?

Well he struggled with JMM throughout his whole career, many people argue he lost the first two anyways.

No one thinks Horn or Bradley beat him, so nothing changes there.

Plus you lose lots of top class victories.

Mosley, Rios, Algieri, Bradley, Vargas, Matthyse, Broner, Thurman.

 

Yeah but in 2011 those first 2 fights were kinda fading into the rearview mirrow. Its not whether Bradley beat him its those being competitive fights. Manny was destroying people before that.

I'd say the best time to do the cut off is after Mosley.

 

He didn't lose anything legacy wise by continuing, he only enhanced his legacy.
