I could be completely wrong, and correct me if I am, but it seems as if Pacquiao has had the single best fighter in Barrera/Marquez on his resume, but fewer solid opponents. What I mean is that if you take out re-matches, Pac has fought quite a few fighters on the downside of their careers. Floyd doesn't seem to have anyone as impressive as Barrera/Marquez on his resume, but has had more solid, prime fighters. I haven't been around long enough to know, but this is my impression. What do you guys think? Am I wrong about saying Corrales/Hernandez were not as good as Barrera/Marquez?
Pacquiao: Barrera, Morales, Marquez
Floyd: Corrales, Castillo, Hatton, Hernandez
Here are the best fighters each have faced in my opinion. I'm not including other guys that weren't in their prime.
