In another world team 7 reminded kakashi of his own team, sasuke was like him, sakura was like rin and naruto was like obito. In this world, team 7 still reminds him of his team but naruto doesn't remind him of obito. He reminds kakashi of someone he considered a father-figure, someone who was his sensei, most importantly that someone was his previous hokage. Naruto Uzumaki reminded him of Minato Namikaze, his team leader.
