Drcitan, you need to pay more attention when you read the manga.
still kabuto underestimaed naruto greatly by just jumping at him with a kunai. he was careless thats the only reason he got hurt besides both naruto and kabuto got knocked out. kabuto could still move naruto couldnt, just like the naruto gaara fight and in that one everybody said naruto won cause he could move in the end with like his chin or something.
