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.

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.

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.

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.
