sakura is the heroine, she was made it by Kishi and his producers. Hinata has the byakugan so of course Sakura's screwed, how bout who would win if Hinata was a normal girl too? besides, all Sakura would have to do is put up some kind of smokescreen and then from there one hit either way the other is dead. But, we all know that this fight will never happen because they are comrades so who cares.
