What is a system qb?

A system quarterback is a quarterback who excels within a specific offensive system or scheme, often relying on precise execution of plays and coordination with their teammates to be successful. These quarterbacks may not possess the same individual talent or physical attributes as other elite quarterbacks, but they are able to effectively manage the game and make smart decisions within their team's system.

System quarterbacks are often seen as products of their system, meaning that their success may be attributed more to the coaching staff and supporting cast around them rather than their own individual skills. They may be criticized for not being able to carry a team on their own or for struggling when transferred to a different system.

Examples of system quarterbacks in the NFL include Tom Brady, who has excelled in the New England Patriots' offensive system under head coach Bill Belichick, and Alex Smith, who thrived in the West Coast offense utilized by the San Francisco 49ers and Kansas City Chiefs. These quarterbacks may not have the strongest arms or most impressive physical abilities, but they are able to effectively lead their teams to victories by executing the plays within their system.
