I thought Bilas was specifically referring to Zion's national popularity/his 'brand'/awareness of him as enabled by social media and video clips. He has a gazillion followers and even pros and celebs know about him. I though Bilas was comparing that with national awareness of Alcindor, and looking for some other comparable. There really aren't many others. Lebron was a huge thing. Lenny Cooke was a huge thing. There was a kid who was supposed to be the Next Jordan, but he... wasn't... and i can't even remember his name now. But, he was hyped on a major level.
