I guess I am to old because this stat is really meaningless to me even though I know a lot of people refer to this stat. Unless there is something I am missing.
If I understand it correctly, let’s say a team like Troy is playing South Carolina. Their (Troy’s) star player plays entire time and team (Troy) is only down 2 points when she gets injured and she misses rest of game. Troy then gets outscored by 25 points. The stat line for the star player is -2 but if another player comes in the game for just 5 seconds before half time and another player on her team makes a shot from half court, then the player that just came in gets a +3 rating for the game.
Or a S Carolina sub comes in and contributes nothing but they outscore Troy by 25, the sub gets a +25 rating?
Am I understanding this correctly? If so then it seems like you would have to know all the circumstances of the game before it means something (but not much) IMO.
