Jon Steven Young is an American former professional football quarterback who played in the National Football League (NFL) for 15 seasons, most notably with the San Francisco 49ers. He previously played for the Tampa Bay Buccaneers, who drafted him. Prior to his NFL career, Young played for the Los Angeles Express of the United States Football League (USFL) for two seasons. He played college football for the BYU Cougars, setting school and NCAA records.
Young left the fledgling USFL after the 1985 season to join the Buccaneers. Two seasons of underwhelming play led Tampa Bay to trade him to the 49ers in 1987. A quarterback controversy ensued as he spent several seasons backing up starting quarterback Joe Montana, who had previously led San Francisco to two Super Bowl championships and would quarterback two more Super Bowl wins. Young became the 49ers' full-time starting quarterback in 1991. He was named the AP's NFL Most Valuable Player in 1992 and 1994, and was the MVP of Super Bowl XXIX where he led the 49ers to a victory over the San Diego Chargers with a record six touchdown passes. During his 1994 MVP campaign, Young set a new NFL record for passer rating at 112.8.
