Football is widely regarded as the ultimate team sport. One player can’t completely change a team’s fortunes the way a star can in basketball, and one player can’t shut down the other team by himself the way a dominant pitcher can in the diamond sports. It takes all 11 guys on the field and the right play-call from the coaches to have success on a given play.
That being said, based on the composition of a team’s roster and the scheme it runs, some players are more important to their team’s success in a certain year than others.
