Jeff was a local boy that played at Mt. Crest, and went on a mission a few years ago, so I doubt he's a recent convert. As mentioned above, he was the one that led USU in that overtime game in Logan a few years ago.
There was a defensive lineman named Crosbie (can't remember first name) that finished up a few years ago. I know he wasn't a member when he was here at USU, so he may be your guy.
