I dunno when Ariza started working with Pacquiao. But Manny looked lean against morales 1 and against Diaz is well. Remember he was moving up in weight and he certainly felt the weight of Morales in the first fight and his power wasn't as devastating gainst Diaz.With Ariza in the corner PAC TKO 7. I just read he started work with Pacquiao in the Diaz fight.Those milk shake has some magical properties. God bless Ariza.
Manny would win in brutal fashion. Castillo could do nothing to hurt him and his aggressive style would so work against him. Now if you're talking Jose Luis Ramirez, it might be a better fight. But Manny still wins on speed. I'd like to see Alex Arguello at Jr. Lightweight against Manny. THAT would have been a war. Alex is one of the greatest featherweights and Jr. Lightweights of all time. Manny might be too fast, but Alex's punches are so sharp that Manny better not take too many of them. Actually, Manny at Jr. Lightweight was not as good a boxer as he became later, so I think I go with Arguello against Manny when we could make 130.
