A marginal player is designated as someone with fewer than 25 career win shares. In draft analysis, this category represents the lowest outcome tier alongside reserves, starters, stars, and superstars. section 3.8
Use the designation in two related analytical ways:
- Segment draft outcomes by career win shares; marginal players fall below 25 win shares. section 3.8
- Remove marginal NBA records before studying scoring leaders by filtering for at least two points per game and at least 20 games played. section 19.3.2

Inspect the R filter that reduces 12,136 player-season records to 6,390 observations before selecting and converting the PPG variable. section 19.3.2
