Plus/Minus is scored as simply
[(points scored when you are on the floor) - (opponent points scored when you are on the floor)] - [(points scored when you are off the floor) - (opponent points scored when you are off the floor)]
The idea is to see how well the team is doing with you on the floor and how well it is doing with you off it. As a result, plus/minus scores aren't "transferrable" across teams -- you can't compare Betty Lennox's plus/minus to say Michelle Snow's. What plus/minus does is gives you some idea as to how valuable a player is compared to the choices a team has to substitute her.
When these "points scored" values are adjusted to a forty-minute game -- in other words, when points scored becomes "points scored per forty minutes" -- one comes up with a figure called "net plus-minus".
The figures for the Atlanta Dream:
Castro Marques: -2.9
In this case, I did not list any player with less than 130 minutes, except for Haynie who has 129.4 minutes.
This gives us an idea of the best possible lineup:
Without Little around, Izi becomes our #2 forward...and she's not bringing a lot to the table.
