Fights that Pacman should look forward to:

Super Featherweight(130 lbs):
Marco Antonio Barrera 63-4
Joan Guzman 26-0 with 17 kos
Edwin Valero 20-0 with 20kos
Jorge Barrios 46-3-1
Juan Manuel Marquez
Rocky Juarez 25-3
Humberto Soto 40-5-2

Lightweight (135 lbs)
Joel Casamayor
Ancelino Freitas
Diego Corrales (i think he will move up in weight and fight in the jr. welterweight division)
Juan Diaz

I'd say the most dangerous opponent for Pacman would be Edwin "el inca" Valero. 20 wins with 20 KOS. 18 of his opponents were knocked out in the 1st round. the last 2 were TKO2 and TKO10. He is 24 urs old and stands 5-7" and also a southpaw like Pacquiao.
