Dave Twardzik stats by season

Start with scoring and impact, then switch views for shooting or the full advanced picture. Career percentages use total makes and attempts.

What these measures mean

Box impact: Estimated points per 100 possessions above that season's league average, from the historical box-score model. Zero is league average; higher is better. Historical defense estimates are included where labeled. This is not the live model's lineup-adjusted estimate.
Impact Rate: A 0–100 score comparing performance within one season. Higher is better. This is a score, not points per possession.
Impact estimate: The season model's final estimated points per 100 possessions above league average, before conversion to the 0–100 Impact Rate score. It includes lineup evidence where available. Zero is league average; higher is better.
Impact Rate rank: The player's place among qualified players in that season's Impact Rate ranking. No. 1 is best. This is a rank, not an impact score.
Value contribution / Season Value: Completed seasons use a fixed-baseline contribution to Career Value. The live season instead uses Season Value, combining that season's impact with workload.
Career Impact Rank: An all-time rank weighted toward the player's best three, five, and ten seasons.

How to read this page

Impact Rate shows how strong a player was compared with everyone else that season. Season Value adds how much he played; completed player-profile rows instead show each season's fixed-baseline contribution to Career Value. Career Impact Rank 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.
