No doubt about that I think you would hard pressed to find even haters not respecting his talent. He's a natural. Things I need to know before I consider him GOAT status:
1) I want to see him in a war
2) I want to see his recovery time after being tagged hard
3) I want to see his heart, maybe after losing a few rounds to see how he deals with it
4) I want to see him against a top notch BJJ artist (shogun was decent)
5) I want to see what happens when fame, money and women come knocking and if that will pose a distraction (that's part of what makes Silva and GSP great).
Once those things are answered I promise to erect (heh heh he said erect) a shrine in his honor.
