they seem to be a bloodline that can control and even match the power of a tailed beast! so why hasn't there been a uchiha junjuriki?
we all know that the uchiha tried to bust a coup d'etat but im sure not all uchiha agreed! there must have been some really honorable uchiha who would use their sharingan for good (like itachi).With the tailed beast being as strong as they are it would make sense to have a uchiha jinjuriki to control it like tobi did if a tailed beast was to break out on a rampage. if anyone is built for a jinjuriki it should be either uchiha or uzumaki. choosing anyone else is a stupid gamble even though the host may be strong. regardless of what i typed i dont like the uchiha much (too emo for me) but credit has to be given. still think Uzumaki's are far superior in every way don't get me wrong (have to represent suckas!) it would be nice to see this so naruto can have a decent punching bag to get strobger on.
because none of the hokage trusted the uchiha to have one as a jinchuriki. not to mention that they would b too overpowered and unstoppable.
also they would rape naruto and then the show would have to b called something esle, that has to b y its called naruto is because hes the 9 tails jinchuriki, if you would have sasuke as the jinchuruiki of the 8 tails kishi would have the show called sasuke.
also there would b nobody able to beat them and kishi would have to think of some impossible way for naruto to defeat this character which would upset a lot of fans.
its not a tradition to choose only people directly related to the kages, gaara was chosen so thath his dad,the kazekage, could use him as aweapon against the leaf. naruto became one because his dad,the fourth hokage,had no other choice given the circumstances. not to mention that bee is only the adopted brother of the raikage and he already had the 8 tails inside him before ever meeting raikage. i think it was just a matter of the leaf never trusting the leaf after the battle between hashirama and madara and it continues on today
