Every NHL team prefers to retain its stars, but sometime issues arise which force a general manager to consider trading away a notable player.
Free agency is often the main reason for such a move, especially if a player is in a contract year and seeking a significant raise. Age can also be a factor, for while a player's name might still have star power, his declining skills combined with a high salary could make him a liability. A rebuilding club sometimes shops one of its best players to bring in additional roster depth. Clashes with a head coach or personal off-ice matters can also make a star player expendable.
Here's a list of the most expendable stars on each NHL team this season, the reasons why they're in that category and the chances they'll be moved this season.
