So how did i fail? No you meant that Naruto and Sasuke can beat him.. and hence they surpassed him. You never mentioned "overall".. And no Kakashi only admit about Naruto.. he didn't say shit about Sasuke.
"kamui kakashi beats her".. sure.. if thats what you want to believe go ahead.. however, Sakura is beyond Kakashi's league.
Ok man, so I said that Naruto and Sasuke have surpassed Kakashi a while ago, by Kakashi's own admittance (he didn't say anything about Sasuke but this was base Naruto we're talking about, before Sage mode, Sasuke as of now is way beyond that). You brought up some irrelevant point about how they haven't surpassed him because they're not as good tactically as he is? Which wasn't something I was arguing in the first place. Irrelevant point.
Now to Kakashi and Sakura, we'll have to disagree there, he's been shown to be able to avoid Sakura's punches fairly easily, he has more than a thousand Jutsu available to him + Raikiri and Sakura really has no counter for Kamui, if he plays it smart, he has more than enough in his locker to defeat her, that's my opinion. The only problem would be her summoning, she could potentially win if she uses that early.
