Hinata could probably beat Sakura and Ino. Certainly not 10 out of 10, but she could.
Anyway, Hiashi is the head of the Hyuga deservedly. In part one during the Leaf's destruction arc you see the ground massively torn up from his rotation because his power is enormous. I haven't seen any other Hyuga do anything like that. If Hiashi dies, Neji is the next most powerful Hyuga, but unless Hiashi changes the Hyuga on his deathbed by removing Neji's mark he won't be the head.
Okay
sakura = Ino = hinata. ( tough to tell , depends on circumstance)
u are right those people are stronger than hinata, but there are loads of ther people who hinata can beat
hinata>sakura
hinata>tenten
hinata>kiba
hinata>ino
hinata>sai
hinata>temari
hinata>and lots of other ninjas
You know,
Sakura = hinata ( can't see any winning. Sakura smash the ground, hinata lose balance, falls. Sakura head for the kill )
Kiba > hinata. ( remember the jutsu where kiba transform to a giant white wolf? Hard to see hinata dodging that or blocking that as it has high speed + power)
Sai > hinata. ( seriously??? Sai can attack from above, sending all his drawings into the fray, = hinata dead)
Temari > hinata.( Hinata is a jonin with powerful wind techniques , she can stand from afar and obliterate hinata from afar. Hinata is shown very supsceptible to mid- far range atttacks. As shown when she literally get blown around the area by pain )
okay, i will let in on 3.
Hinata > ino
Hinata> ten ten.
Hinata > lots of other ninjas ( genins)
