Every player on a team matters. Every player has a role to fill. Some are mentors to help younger players. Other are young players; the stars of the future who are hoping to make it big and have a long and lasting career. Then you have the star players that the team depends on. The Philadelphia Flyers have players in all of these categories, and need to find a way to make it work.
The Flyers have roughly two dozen players on their roster, and about the same in the minors, who can be called up at any time.
