Yeah, he did fight Perez at 130, good point. Sal had a pretty solid frame for a feather. I believe he would have found success at 130. 135, I dunno, but most likely 130.
I'd take Sanchez over Chavez with decent confidence at 130. Sal operated across 4 dimensions in the ring
I rewatched Sanchez vs Nicky Perez last night. I hadn't seen it since the days of having it on VHS. Yeah, I would fancy Sal by decision over Chavez at 130.
