Why does this stat matter for fantasy?
Plus-minus can be an indicator of potential playing time for bench players. A high plus-minus is suggestive of a player who helps his team win when he is on the fllor even if he does not put up great individual stats. If you are looking for players who could be in line for increased playing time, plus-minus can be used as one data point to decide if you should add them.
