Naruto was freaking like 13!!!! There was no way he would have been able to control kyuubi!!! I could Sarutobi could have done a little more for Naruto, like tell him who his father was, but I think Sarutobi did as much as he could for Naruto without favoring him.we know that kisame is comparable to hachibiii...even more i think... if sarutobi was to be so powerful then he could atleast help naruto have control over kuyuubii rather than sitting in white cloak like dumbass and enjoying the sexy no jutsu...
