NBA combine is by invite only and he would not get an invite
As for his name, it is true that XZaiver made a comment that the change was “personal” and he had no comment. Then later it was discovered that the B1G changed a rule that made everyone be listed by their legal names (which is beyond dumb). But if you watch the interviews with coaches/players or follow them on social media you will see that everyone calls him X and that seems to be what he prefers and goes by. So I’ll just chalk up X’s response about the name being a “personal” change as him being generally private and short with the media.
