Who matches up best with Pac?

[Pavlik]

As crazy as it sounds, I think Pac - Valero would be a very close match. Neither fighter would give an inch, Valero has absolutely 0 defense but he is ALWAYS throwing and he throws the type of bombs that I can see Pacman walking into. The only thing I worry is Pac's one punch power. Valero is just a fighter who is balls to the wall and overwhelms you with his hands at his hips and while I think he can connect to Pacquiao, I don't know if he could KO him before Pac got to him.

That would have the potential to be one of the most fun matches to watch out there. Two guys who swing with little regard for defense.

Absolutely!!! Valero is one scary beast. I'm scared for PAC in this one, PAC has shown over and over again that he has below if not average defense and can get hurt big time. But I honestly would like to see this one happening.
If PAC beats Valero and win it by knockout I can say that PAC can already retire and he is absolutely the best superfeatherweight of all time for beating a naturally much larger man with the highest knockout percentage and most1st round kayo

You would give him the best superfeatherweight of al time for that? So you think he would beat Mayweather or Azumah at the weight? I can't even see him beating Corrales or Casamayor at the weight. Mayweather would destroy him at 130. Also Pacquaio isn't that small weighing in at 144 means that he's at least as big as Mayweather in his walking around weight, and larger than Valero from what I've seen.

I'm taking into consideration that PAC started really light as compared to fighters you've mentioned that fought way longer than him as a superfeather/or heavier. For a naturally small framed fighter PAC's achievements are way more of a FEAT than the fighters you've mentioned. To add you mean Valero and Mayweathers walking weight hovers around 140'ish? Dang those two definitely weighs alot more during fight night IMO.
