In the first trailer for “American Underdog,” Kurt Warner (played by Zachary Levi) is called into the office of St. Louis Rams coach Mike Martz and is grilled about why he should get the chance to be the team’s starting quarterback. 

“Go ahead then, tell me,” Martz, as played by Chance Kelly, says. “Why a team worth $800 million and with the most complex offense ever built should put you in the driver’s seat? You’re too old to be a rookie, too green to be a pro. So why in the world would I give you this shot?”
