The Target Breakdown Report shows how an offense is distributing targets to the different skill positions on the team. Running backs on teams with higher RB target share are much more likely to have better fantasy value, particularly in a half or full-PPR league. This obviously applies to each position, and can be a helpful in making decisions about what to do with players on specific teams. Ideally, target players with high usage at their position and move on from those with low usage.
