Quarterbacks generate more discussion than any other position in the NFL. They're the highest earners, receive the most credit for wins and shoulder the majority blame in defeat.
Typically, a club's playoff chances live and die with the quarterback's overall performance during a given year. If he struggles or suffers an injury, his respective team should prepare for a rough season unless a competent backup can run the offense at a high level.
Despite their position in the spotlight, quarterbacks also need help. Only a few can elevate an average supporting cast. Russell Wilson and Patrick Mahomes come to mind.
