@Dizmiz if Naruto had the time to do that he could have just put his arm through his face. As it was he barely had time to put any defense between him and Sasuke.

Besides, we were arguing whether the TSBs or Naruto's own actions was faster, not the lethality of either action. Obviously putting a TSB though Sasuke's face wouldn't have been fast enough. So he did what he could and blocked.
