I expect every top 10 (or so) player to realistically believe they are the best player in the world.
He is not, but I'd be surprised if any of those guys didn't think that way.
For right now (excluding the injured players) I'd have him at 8th
1. Giannis
2. Lebron
3. Harden
4. Kawhi
5. Davis
6. Doncic
7. Jokic
8. Embiid
9. Butler
10. George
Durant and Curry are both better than Embiid if they return to health, so that would potentially drop him back 2 spots. If he could stay healthier, I'd probably have him ahead of Jokic and maybe Doncic (though that might only be for this year). Be hard to have him higher than Davis.
