The big problem is unless you search and find out Harper is a member of the church or follow his Instagram you would never know that.
So for example if I am a Rangers fan watching baseball, I have heard of Harper, but I would not add or search his name or about him or his Instagram account. So the likelihood of me knowing he is LDS is pretty slim.
But let’s say I am a Dolphin’s fan and I am watching the game last week and they mention that Taysom played at BYU, well I probably know enough about college football that I would assume that he is a member of the LDS church.
That is why I am saying Taysom is doing more for the church as far a publicity in general than Harper is.
But if I am a Nationals fan I probably know Harper is LDS.
