The quarterback is the offensive leader in gridiron football, typically lining up behind the offensive line and touching the ball on nearly every play. Widely considered the most important position in team sports, quarterbacks are often the highest-paid players in the NFL, though a star's large salary can create a "catch-22" by limiting a team's ability to sign other talent. A famous example of strategic sacrifice is Tom Brady, whose consistent pay cuts with the New England Patriots allowed the team to afford stars like Randy Moss in 2007. On the field, the quarterback's duties include calling plays in the huddle, receiving the snap from the center, and either handing off to a running back, throwing a forward pass, or scrambling to avoid a sack. The role varies greatly by offensive system, from pass-heavy "spread" offenses to run-focused "triple-option" schemes, and modern players like Lamar Jackson are known for their rushing ability.
