Well most peoples eyes and more importantly the tale of the tape and the weighing scales say differently.
It is about the lowest weight you can make and still be effective. And I do not believe Pac can't make 135. Against Hatton just 2 yearsa go, he weighed 138 lbs. He most definitely can make 135 if he really has to. I am sure Alex Ariza can adjust his nutrition intake if necessary, Right now he obliges Marquez to a 144 lbs fight because he is already comfortable at that weight.
