mind explaining why that one punch was enough to knock out Neji in the fight vs Naruto while hes getting the crap beaten out of him vs the sound nin and still going? Naruto isnt exactly stronger then something that creates a massive hole in Neji's arm. Sorta seems like a plot device as Naruto certainly shouldnt have won that battle by just doing what he did, Neji was alot stronger then that as we see now.
Brings up the question of whether Naruto deserved that win against Neji in the first place or if it was just convient for him to win.
