Four years later, that passion remains.
While Lark was serving a mission in St. Petersburg, Russia, two highly touted QBs decided to join BYU's program — Riley Nelson, a transfer from Utah State, and Jake Heaps, a prep star from Skyline High in Washington.
Of course, Lark found out about those additions to the roster during his time in Russia.
"I had lots of people telling me to transfer. But my heart was here at BYU," Lark said. "I knew I was going to come back to BYU, no matter what. I love the football program, I love everything about BYU. There's no way I was going to leave. I wasn't scared of the competition. I was excited for it."
Lark, a 6-foot-2, 200-pound sophomore, returned from Russia in December and immediately began preparing for the upcoming season.
