Looking at the last ten seasons of fantasy baseball projection accuracy, measured by Mean Absolute Error (MAE) and normalized via z-score so results are comparable within each year's participant pool. Read more about the methodology here.
System icons: ⚾ are for base projection systems and ◇ is for the aggregate systems that combine multiple base projections.
Note on Average of Projections: This system uses the base projections available in a given year and averages them together. The specific sources included vary by season, drawing from non-aggregate systems such as THE BAT, ZiPS, Steamer, Clay Davenport, and others available at the time.
Legacy systems (Fangraphs Fans, CAIRO, Pod, MORPS) are no longer active but are included for historical context. Use the "Include historical sources" checkbox in the All-Time view to show or hide them.
