You can bring up Kawhi, but he did not force his way there. Toronto gave up their best player for him and Kawhi didn’t even want to play there.
Pre KD-Warriors won a title built almost exclusively with guys they drafted. Same with all the Spurs titles.
Really the only examples that fit your criteria are the Lebron/Wade/Bosh Heat and the KD Warriors. And those warriors could have won without KD.
