Pac is beating everybody under 135 lbs.

The only real defining fight for him now is a rematch with Berrara but I don't think Berrara is going to want to take that fight.

Joan Guzman may turn out to be a long term rival if he lives up to his potential but the one guy who I would love to see him fight is Juan Diaz.

I think Diaz may be to big for him as he's fighting at 140 right now, but at only 5 ft 6 he may be willing to get down to under 135 to face the pacman.

That would be one hell of a fight in my opinon.

So in summary, Berrara or Diaz, there really isn't anybody out there to compete against Pac right now.

Oh forgot Barrios and Juarez, another two potential great fights, but I think Pac will be too strong for both.
