Re: SM Naruto surpasses both Jiraiya and Minato
Naruto surpassed Minato in terms of mastering Rasengan - Kakashi mentioned it referencing Rasengan.
Naruto surpassed Jiraiya in terms of mastering Sage Mode - Fukasaku mentioned it referencing Sage Mode.
Naruto surpassed both of them, overall, as a shinobi - Fukasaku said this. If Fukasaku meant Rasengan or Sage Mode, then he'd have mentioned it; Fukasaku didn't even know FRS existed until Naruto used it against Pain.
Though SM Naruto has surpassed Minato, Minato is an interesting one. With his skill set he can still fight people tiers above him, even though he doesn't have the power to match them. A perfect example being Minato vs Obito.
