In American football, the starting quarterback is typically viewed as the leader of a team. The quarterback is considered the most important position on the field and among the most important positions in team sports. They are among the most high-profile athletes in North America and have been described as akin to A-list celebrities; in the United Football League, such quarterbacks benefit from national television exposure and in-game action that they may not get as backup or practice squad quarterbacks in the National Football League; former New York Guardians starter Matt McGloin, former Dallas Renegades starting quarterback Landry Jones and former St. Louis Battlehawks quarterback AJ McCarron all cited the ability to have their friends and family see them play professional football as reasons why they chose to play in the league. The success of an American football team often rests on the quarterback; thus, teams will go to great lengths to find a franchise quarterback to build around for the long-term goals of the team.
