if we begin making our tailgaiting a missionary tool we will begin to scare BCS conferences away. There is already a rumor that Big12 not interested in BYU due to BOT saying our athletic purpose is for missionary purposes.
That might be the case but you can spread the word though actions (quietly)
If I ever were to join the church it is because of the quiet example that many people, including BYU athletes have set.
Example: today I was talking to KVN. He said he had no interest in the church until he got to BYU. He now embraces the Mormon Church.
