When looking at NBA players who have improved, it’s easy to mix up players who just got more playing time with players who have truly upgraded their games.

In order to determine which players have truly upgraded their games, the best tool to measure with isn’t traditional box-score stats like points, rebounds and assists because they don’t account for minutes. Player efficiency rating (PER)—John Hollinger’s per-minute, single-number metric—does a much better job of evaluating improvement.

To determine the most improved players, I looked at players who were qualified for the PER title and in the top 100 in PER who had improved the most. They are ranked here by how much they improved in the metric from last year.
