How to read these numbers
- Confidence in the call
- How clear-cut this start/sit call is — how decisively the player beats the alternative he competes with (for a starter, the best player on your bench; for a bench player, the last one in your lineup), on both projected points and the overlap of their likely ranges. A clear play reads high; a genuine toss-up reads lower. It rates the decision, not the player’s own volatility, and is not a measured accuracy rate.
- Floor
- The 20th percentile of the same simulated distribution.
- Ceiling
- The 90th percentile of the same simulated distribution.
- Opportunity score
- Expected points from projected volume alone, before any efficiency of this player’s own: each projected touch and target valued at the positional average for the scoring format.
- Matchup grade
- The opponent’s points allowed to this position per game, weighted toward recent games, then graded on a curve across the 32 defenses.
- Implied team total
- The points the betting market expects this team to score, derived from the game total and the spread. Market-derived, not modelled by Nuvela.
- Trend
- The direction of his scoring across the trailing window, classified as heating, steady or cooling.
- Touch share trend
- The same classification, measured on his share of team touches rather than on his points.
- Consistency
- The share of his games that landed within a set band of his own per-game average.
- Boom rate
- The share of his games that finished inside the top 12 scorers at his position for that week.
- Bust rate
- The share of his games that came in under half of what he was projected for that week.
- Vacated touches
- Carries and targets belonging to team-mates who are ruled out, on IR, or listed as non-participants for this week, taken at their recent per-game rate.
- Defense funnel
- Whether the opponent’s rush defense and pass defense are far enough apart to push offenses one way. A gap inside the band reads Neutral.
- Game script projection
- The expected state of the game for his team — favoured, level or trailing — taken from the closing spread.
