Murdered might be too strong of a word, but Diaz is definitely superior on the feet. He devastated Smith and Shamrock. Do I think Nick would win, probably not because I don't see him stopping GSP from getting the takedown, but it would be an interesting fight.
Shields has no chance against GSP. It would be a mirror of GSP vs. Fitch.
