If Giannis didn't play in Milwaukee, I think he'd already be the face of the league. And to be clear, it isn't just that he plays in Milwaukee, it is his personality plus him playing in Milwaukee that leads to it probably won't be him (though it should be). I'm guessing it will probably be Doncic. He has the sort of fiery personality that will make him very popular and he is obviously incredibly talented and has already had a decent playoff run when he had incredible stats.
