Traveling for work for years people know who BYU is for Football and have watched a lot of their games.
Moved to TX 6 years ago, and most know who BYU is, I have a BYU mask, and get comments on it a lot, even when I Uber people see if and comment.
This last week or so many talk about Wilson and what is going to happen. So I would say lots of people know about BYU besides just Mormon.
Are they some yes, I would say some, but I wouldn’t say majority.
