The upper right half of the matrix equals the +/- for the respective pair.
The lower left half of the matrix equals the minutes the pair were on the floor together.
The diagonal (where a player is paired with himself) is the +/- for the player by himself.
The upper right is the +/- per minute that the pair were on the floor together.
The lower left is the +/- projected for a full game (i.e. 40 times the per minute number).
The n/a means the pair weren’t on the floor together.
Morrissey and Walker turned out to be a surprisingly effective back court combo.
