Why Sion James ranks #321
The current model starts with box production, checks it against multi-season lineup evidence, caps that correction, then accounts for how many minutes the player was trusted to play each game.

RAPM estimates lineup impact while controlling for the other nine players on the floor. The multi-season blend, current total model, and current offensive/defensive split are separate estimates, so they need not equal one another. hussEyquation uses the multi-season signal as a bounded correction, not as a standalone verdict.
What the point estimate meansLow precision
The model's 80% impact interval is -2.59 to +1.85. Exact ordering is difficult when many players have overlapping estimates.

Impact Rate shows how strong a player was compared with everyone else that season. Season Value adds how much he played. The career ranking rewards a high peak, a long prime, and repeated seasons near the top. Older seasons use clearly labeled estimates where the NBA did not record today's full set of statistics.
