Elaborate on how those wouldn't have worked, I already know for a fact that Naruto wouldn't last a second against a barrage of Shuriken and fuma Shuriken and strings combo using tajutsu alone, He get beicected because of chidori spear, he won't be able to defend against 9 Bijuu sized CT slamming him at the same time while charging up his attacks, he won't be able to avoid core less CT, he won't be able to survive if he is teleported right between their final clash, and most importantly he can NEVERfight Sasuke if he had his last bit of chakra drained instead of Sasuke just doing the usual and clash with Naruto's rasengan.
