I pick apart some of Floyd's wins because I think context is important when discussing quality of opposition...etc. That being said, I just can't find a way to fault or discredit Floyd's fights vs Chico and/or Hatton. Both of those fights were ATG performances by Floyd.

Floyd has had difficulty with aggressive maulers who were able to close the distance quickly and force an inside fight (Castillo, Jesus Chavez, Famoso, Hatton and Maidana). The other style that proved difficult was the much larger Oscar, thanks to his effective jab. Floyd was an ATG at 130, so guys like Azumah, Frietas, Casameyor...etc., would've given him some issues, but none, imo, has the style, athleticism and complete toolset necessary to beat Floyd.

Chavez is the one guy who, at that weight, was complete enough and heavy handed enough to pull out the win. I see that fight as 50/50, with JCC's work rate and body attack getting the close decision.
