Holt, Sta. Cruz and pac all have decent enough power to KO anyone in their division. He got tagged quite bit during these fights. I'm basing Hatton's chin in his last 4 fights. It's not bad but basing from what i saw i think diaz has the better one IMO.
diaz is one tough sonofabitch, but as we saw against pacman, heart & toughness only get you so far. hatton is pretty damn good (at 140) the chins on these two are a tough comparison, i'll go with hatton.
