Yeah you have a solid point, but I still think he should be mentioned considering how well he's been fighting in weightclasses bigger than his own and still carrying good punching power. Pac could fight at lightweight if he wanted to but still ko'd Hatton and stopped Oscar at higher weights. David took a lot of punches but got ko'd brutally.
i agree bu there are 2 things 2 consider..... 1. oscar and diaz are both tough guys to say the least 2. maybe his power is more fierce at the weight he's most comfortable at, which appears to be 140 but anyways i dont think theres a clean cut answer but here r some guys that r worth a mention.... abraham haye valero maidana pac ortiz donaire gamboa bailey adamek
