Most everyone on this board seems really pro Itachi, Kakashi sux. I think Kakashi will be able to jump into the middle of these two and fling them to the side like on the roof of the hospital.

I think he might get a chakra burn from Naruto, and Sasuke might get in a slight grazing taijutsu shot, but that is all.

Kakashi has never been touched. He has been ninjutsud by Zabuza's water prison and Itachi's Mangekyou, but that is it. (I will give Kakashi the benefit of the doubt and say that he really did let Zabs tag him just to get his scent on him. Plot device, but still adequate to say that he has never been out taijutsu'd)

Yeah, Kakashi cowered in the face of Oro, and Oro kind of cowers in the face of Itachi but...

Gai considers Kakashi THE ELITE ninja to compete with, and Itachi gave a warning regarding taking the threat of Guy seriously.

I tend to think that the x vs y things on this board are silly.

First off, the storytelling motivation will be the bottom line

second off, I think a Rock Paper Scissors relationship is just as plausible. Who knows what the elder Hyuga would do against Itachi. Enough people have said that they are THE ELITE Konoha blood limit, His body was a point of contention that almost led to a war, and did lead to the willing suicide of his hateful brother.

...where was I.

Kakashi will break these two up like the gennin they are.
