You would have a point if the scan didn't literally show them going back and forth without one out maneuvering the other in speed. If she out performed him in that area, he wouldn't have been to counter. The reason why she got the best of him, was literally because her CQC was better.
Consider that all of the enemies know of her attack move, and that they would all be suspecting of it if she jumps in the air. That's not even counting what Boruto is capable of ninjutsu wise.
I'd like to see her punch her way though Surging Sea, lmfao. Or a throwing Rasengan.
Naruto was able to go back and forth, and even outperform Sasuke a few times, with his clones. Despite Sasuke not only being faster than him, but also his base CQC being better.
That's not even counting the fact that he had a 3T Sharingan. So... you know the answer.
I enjoyed this chapter quite a bit. Seeing Metal Lee do a jutsu was sweet! Namida's secret jutsu is awesome! Konohamaru chastising Kakashi was lulz. Oh and seeing Kakashi's face was so cool! Happy they're genin now and look forward to next week.
