@clawfist: The thing is Sabretooth has always been physically better than Wolverine. He's always been faster. He's always been stronger. And during a fight with bone claw Logan, Wolverine also admitted Sabretooth's healing factor. Now while I don't necessarily believe due to Logan's over the top feats of healing when he has the adamantium skeleton to heal from, the statement can be taken with a grain of salt, but Creed heals just as fast IMO. Regardless, the whole Wolverine/Sabretooth rivalry for decades has shown if Wolverine fights like Sabretooth, he will lose. So just a savage, mindless animal, he loses. So if Logan just fights on a reliance on pure stats, he will lose. Wolverine has stated the man can beat Sabretooth whereas the beast fails. So as Logan has gotten better as a fighter over the decades, the gap between how effective Creed is against him has widened tremendously.
So I'm not disagreeing with your statement that Wolverine can't cut Creed to ribbons with a splash of realism. But he's only done it like once, though and that was with the Muramasa blade and they've had so many fights as is. Wolverine has the advantages due to skill and adamantium, but Creed is more than physically superior to Logan. In comparison to Cyber and Omega Red, yeah, he falls flat, but that is mainly due to them having other advantages and stats over Wolverine that Sabretooth doesn't have. And he has a hard time compensating against ie carbonadium tentacles, adamantium skin, poison claws, etc. Creed just comes as he is. Maybe I'm misreading your point, but I disagree with the notion physically Creed isn't superior. It just isn't enough to make him win anymore.
