I think he beats both. He only sucks against southpaws and Canelo and especially JCC jr are ridiculously overrated.
Paul would be vastly out weighed on fight night and has nothing to keep Junior off of him. I'm FAR from the biggest Junior fan but size does matter.
I completely disagree that he only sucks against southpaws. He gets hit with any punch thrown, not just left hands
Chavez probably wouldn't outweight him by that much. In the Lara fight, Williams rehydrated to 170, and that was held at the junior middleweight limit.
I would love to see it just to watch PW lay on the canvas unconcious again but really both guys would take alot of heat for taking on him. Both guys have a good punch and PW resistance is gone.
