Who is the greatest NFL quarterback of all-time?

Response:
Different people have different opinions when ranking professional football players in the NFL. Both individual and team metrics are considered when determining the best quarterback. Key individual metrics in the NFL include individual passing metrics (such as passer rating, number of passing yards, and number of touchdowns thrown) and individual awards won (such as the NFL Offensive Player of the Year). Key team metrics in the NFL include the team's win percentage with the individual as the starting quarterback and the number of conference and Super Bowl trophies won. Opinions vary, but many people consider Tom Brady to be the greatest NFL quarterback of all-time due to his individual accomplishments, his seven Super Bowl victories, and the dominance of the New England Patriots during his time as their quarterback.
