Who can beat beat Pac? (none welterweight)

Considering that Pacquiao been looking like a monster against some welter weights He hasn't fought a welter weight yet so I've no clue what your going on about. Clottey and Berto would get him. Hatton shot...Hoya...drained. Asterisk goes next to those names on his resume. The Pacwagon is pretty ****ing annoying already.

I cant think of anyone @ 140 Its very impressive if you think about it. Its like if some welter weight cleaned house by beating some of the top WW then moving up to face Paul William. Manny win or lose is something special. Shot or drained it doesn't matter he's still looked like a monster against them and he still beat them. Hatton wasn't shot, but after Pacquiao now he is.

Considering that Pacquiao been looking like a monster against some welter weights and has easily beaten up some of the best light weights. Its there any fighter who you can see has a chance against Pacquiao that isn't a welter weight. If Pacquiao stayed at 140 or below would've he had ever lost again? If you believe so who and perhaps you like to elaborate why? Anything can happen anyday.
