"there's an envy I've always carried for people who can be so sure of who they are as to share so openly about their beliefs—no matter their faith, no matter where I've travelled."

Great sentiment. I love that this IS a strong component of the LDS faith, but members of the Church don't have the corner on having faith, or sharing that faith. I recognize, like the OP, that being around truly authentic people is awesome. Kalani is great for BYU, we are lucky to have him, and other coaches that not only help our team to be better football players, but better men.
