Final answer:
NFL quarterbacks utilize both personal power—like athletic ability and leadership skills—and positional power stemming from their role on the team. They must work on their physical and mental skills due to their critical role in leading the team's offense and influencing game outcomes.
Step-by-step explanation:
The ability to be a starting quarterback in the NFL is extremely rare, and those players who achieve this position are able to utilize various types of power. In this context, power can refer to personal power, such as athletic ability, leadership skills, and decision-making capabilities. It also includes positional power, which comes from their role and status within the team and league. Successful quarterbacks must continuously work on both their physical skills and their mental acumen, as they are responsible for leading their team's offense and often play a critical role in whether the game is won or lost.
