I just have to say that was definitely a cool fight. But a lot of people are getting it wrong about the elbow. After Naruto knocked back the girl's sword, he tried to elbow her while she was still off balance. It was the guy who blocked Naruto's elbow with the hilt of his sword, and then she flipped over him and attacked Naruto. If you notice, the guy told her not to cut them, meaning they weren't trying to hurt anyone either. They were probably just trying to subdue Naruto, Sakura, and Sai so they could ask them about Sasuke. Anyway, when she tried to attack Naruto, he summoned the kage bunshin which blocked her attack.
Then Sakura and Sai attacked them. Sakura was knocked back, which forced Naruto to run and catch her. But Sai's attack connected and sent the Cloud girl flying in the opposite direction. Which pretty much means this fight was a draw. I think this shows the skill of the Cloud nins because it was 2v3. Also, realize that they were trained by the Cloud Jinchuuriki, so of course they would be strong. Imagine if Naruto had a full time apprentice to teach, he or she would be crazy strong. Just look at Konohamaru, he was strong enough to land a Rasengan on one of Pein's bodies only because Naruto taught him the move just before he left the village with Jaraiya.
I think everyone is underestimating the Cloud nins for no reason at all. I think it makes sense that they're strong. Maybe not all of the Cloud nins are this strong, but the ones trained by Killerbee should definitely be strong. But yeah, the Kage Summit should be really interesting. I wonder how Gaara will react to all of this.
