I'm trying to think of any times that I've ever heard that brought up about him, and I can't think of any. Not anyone outside of mormon media anyway.
I suppose that Bucks fans probably know about his mormonism and that Bucks broadcasts have mentioned it at some point, or maybe in some local interviews he's done or something, but on a more widespread, national level I don't think I ever remember it being mentioned.
It's time for people to stop talking about these guys being "ambassadors for the church" or whatever you want to call it. Next to nobody knows that they're mormon in the first place, and pretty much nobody cares that knows, except mormons and BYU fans.
