If Werdum can regain the lineal belt [the TRUE hw championship title] from Overeem, and unify it with the ufc belt from Cain, then he is the true HW GOAT.
Yeah, that's a good fight. I think Cain's standup skills and his chin are better than Wedum's. I also think that Cain's hands are heavier than Werdum's. Cain is a better wrestler, of course, so he is the favorite. BTW, the Werdum's BJJ is amazing, i am sure that he can sub Cain if he got the opportunitty.
I bet on Cain, and i also think that the better and safe way to his victory is keeping the fight standup.
