We chose to measure a player's value using John Hollinger's estimated wins added (EWA) statistic. Simply put, EWA measures how many wins a player adds to his team's record compared to someone you could sign to a 10-day contract (to put it nicely, a replacement-level player). Basically, the metric combines player efficiency rating (how efficient a player is on a per-minute basis) with playing time and comparative value. Hollinger offers a far more detailed explanation, but for our purposes, just remember that EWA measures wins added and that LeBron James led the league at 32.3.
