Stick, Skill, Carry, Edge, NTV, and TTV
The public performance ratings use a league-relative scale where 100 is average. The distribution is widened so excellent and poor seasons are easy to distinguish. Missing performance data displays as an em dash rather than a fake average score.
Stick
Stick asks whether the player's performance is supported by repeatable underlying ability. It uses expected outcomes, contact quality, plate discipline, bat speed, pitch quality, command, defense, speed, and other skill indicators. High Stick suggests the player is not succeeding by accident.
Skill
Skill measures the player's own production and impact relative to his primary role or position. Starting pitchers, relievers, and each hitting position are normalized within their own competitive pool, with a league-wide fallback for small samples. Skill does not compare the player with his teammates.
Carry
Carry starts from Skill and compares the player with the measured support around him. Great production receives more Carry credit when the rest of the team is weak and less when the player is surrounded by strong performers. A skill gate prevents average players from receiving inflated Carry merely because their teammates are poor.
Edge
Edge is the flagship complete-player rating. It combines the legitimacy of the underlying skill profile with actual individual production and team-relative carrying power.
Weighted Edge = 40% Stick + 30% Skill + 30% Carry
Offset average = ((Stick − 100) + (Skill − 100) + (Carry − 100)) ÷ 3
Base Edge = Weighted Edge + Offset average
Final Edge applies a light positional multiplier to Base Edge. The adjustment ranges from 0.95 to 1.04, rewards scarce premium positions modestly, and uses the highest listed weight for multi-position players. Two-way players receive 1.04.
Longevity Index
Longevity Index estimates how well the player's skill set should age. Discipline, contact, command, and versatility generally age better than profiles dependent on speed, defense, max-effort velocity, or one-dimensional power.
Contract Efficiency
Contract Efficiency compares projected production with salary and below-market control. Scores above 100 represent favorable commitments; scores below 100 represent contracts that cost more than the projected performance supports.
NTV: Neutral Trade Value
NTV is the roster-independent asset value. It combines performance, contract efficiency, control, age, longevity risk, position, scarcity, confidence, prospect pedigree, and downside severity. Zero is neutral, so harmful contracts and declining assets can become meaningfully negative.
TTV: Team Trade Value
TTV starts with NTV, then adds organization-specific context such as roster fit, positional need, overlap, contention window, and the other players moving in the trade.
