What is the "QLs" on the SquadQL app (MLB)?

QLs (QL Score)

Short:: QL Score is a player score based on your league settings to allow for player comparison in non-point leagues.

Long: QLs (or QL Score) is the measurement of how far above or below average a player is based on the stat categories specific to your league. This accounts for all batters and pitchers. While a player may have a negative QL Score, he may be a good option still if others at his primary position are below him.
