Gomi is a fucking warrior, one of the top 5 P4P fighters
but i would say that he still retains his submission weakness. granted he's only lost to the best sub artists like Aurelio and Penn, but Sudo is way up there in the submission fighters chain, high enough to catch Gomi i think.
Sudo's got a major chin, and can recover well. against Mike Brown he took a GnP beating from a superior wrestler, but like all wrestler's he's fought, he caught him anyways.
