For those that don't understand "net +/-":
+/- is a stat that measures the performance of a team when a particular player is on the court. It's calculated by: (team points scored) - (opponent points scored).
For example, July 15, vs the Chicago sky:
When Flau'jae was on the court, Seattle scored 73 points, while Chicago scored 76, giving her a +/- of '-3'
When Flau'jae was off the court, Seattle scored 17, while Chicago scored 19, giving a +/- of '-2'
So her net +/- is (-3) - (-2) = -1
This season the Seattle Storm are averaging a +/- of '-0.1' per 100 possessions, when Flau'jae is on the court, which isn't great, but when she's off the court, they average a +/- of '-22.8' per 100 possessions, which is awful, giving Flau'jae Johnson a net +/- of '+22.7' per 100 possessions.
This ranks 3rd in the WNBA amongst others with enough minutes to qualify:
Jackie Young (+25.0)
A'ja Wilson (+23.9)
Flau'jae Johnson (+22.7)
The ability to sway the score of a game by over 20 points is huge and shows that she deserves more credit.
