The NFL has plenty of game-changing stars, but it's ultimately still a team game.
Even the best players in the league need talent around them to make life easier.
A quarterback needs a functional offensive line and pass-catchers who can optimize the passing game. A running back needs to be in the right scheme with adequate blocking in front of him.
On defense, even the best pass-rushers can be neutralized if the offense only has to worry about them. A superstar can't make up for a bad secondary. The list goes on.
Looking across the league, there are some really talented players who are going to have a hard time living up to their potential this season.
