its was made clear in the manga that the SO6P descendents were the uchiha and senju, thats why both have SO6P level abilities and and EVEN the core jutsu of the sage i.e. WOOD STYLE and RINNEGAN, uzumaki was brother of the senju clan NOT SO6P, but senju, so they would have some relation to SO6p but not enough to relation or important material to link them RIGHT to the SO6P, example, the uzumaki YES does dress like the sage and have priest like jutsu AND also has perfect sealing jutsu that can seal tailed beast BUT thats all that links them to the sage lol and they only have that to SHOW the greatness of there clan BECAUSE of the relation to the SO6P through the senju, those facts about the uzumaki isnt even enough to bump the senju down from there spot lol senju has way more facts linking them to the sage PLUS!!!! it. was. already. stated. in. manga. ppl, you guy are basically saying kishi is wrong lol i can sit down and come up with diff. ways this story could go ALL DAY TOO, but at the end of the day you have to go with facts from the creator of the manga FIRST and then work your way forward from there.
