Purpose
This platform provides college coaches, recruiting coordinators, and analytics staffs with pace-adjusted impact ratings and traditional performance splits to evaluate grassroots talent objectively.
10
Sample Size Qualifier
Players with 100+ minutes played are flagged as 'Qualified' (Yes). Small-sample outliers (<100 min) are preserved in the full database but filtered out of the executive leaderboards to maintain statistical integrity.

2. ADVANCED VALUE & IMPACT METRICS
13
BPM (Box Plus/Minus)
An estimate of points per 100 possessions a player contributed above or below a circuit-average player (0.0). It combines individual box-score stats, team efficiency, and positional baselines.
14
OBPM (Offensive BPM)
The offensive component of BPM. Measures individual scoring creation, shooting efficiency, playmaking, and offensive turnover avoidance relative to circuit average.
15
DBPM (Defensive BPM)
The defensive component of BPM. Captures defensive playmaking (steals, blocks, defensive rebounds) and foul discipline within the team's defensive context.
16
PTS/TSA
Points scored per True Shot Attempt. Measures pure scoring efficiency accounting for 2PT, 3PT, and trips to the free throw line (PTS / [FGA + 0.44 * FTA]). Values above 1.15 indicate elite grassroots efficiency.
17
TS% (True Shooting %)
A comprehensive measure of shooting efficiency: PTS / (2 * [FGA + 0.44 * FTA]). Represents true accuracy factoring in three-pointers and free throws.
18
eFG% (Effective FG%)Field goal percentage adjusted for the added value of the 3-point shot: (FGM + 0.5 * 3PM) / FGA.

4. PLAYMAKING & PACE-ADJUSTED METRICS
28
A:TO (Assist-to-Turnover)
Assists divided by Turnovers. The definitive metric for primary decision-makers. A:TO > 2.0 indicates elite guard ball security.
29
Per 100 Possessions
Normalizes all counting statistics to a standard 100-possession game, eliminating pace bias between fast-break teams and deliberate half-court systems.
30
Stocks/100
Combined Steals and Blocks per 100 possessions. Highlights active defensive disruption and floor coverage.
31
%Team Metrics
The percentage of the team's total production (Minutes, Points, Rebounds, Assists, etc.) accumulated while the player was on the roster.
32
33
5. TEAM EFFICIENCY METRICS
34
Off / Def RatingTeam points scored (Off Rtg) and points allowed (Def Rtg) per 100 possessions.
35
Net Rating
Offensive Rating minus Defensive Rating. Measures overall team point differential per 100 possessions.
36
