Show me evidence of other elites in the clan besides Hiashi and Neji. Also, Hiashi was quite clear, Neji surpassed the main household. Neji had already been stronger than Hinata for years, so him reiterating a fact he already knew since they were children is pointless. He makes it quite clear that Neji has surpassed the main house in skill.and by surpasing Hiashi means the inheritor of the main branch Hinata (or even Hanabi) being under Neji during that time
and yes Neji is an elite but there are also other elites in the clan
everyone of the known others are literally Jounin
if Neji was still alive he might've been the clan head if there was reform, unless Hanabi currently is some uber elite
Neji lacks pure byakugans though and we even saw this in Naruto were Hinata's byakugan range was greater then Neji
while Neji at a young age mastered more GF techs
Also, Neji's KKG was said to run deeper than any other Hyuga clan member, explaining his innate talent.
