Scoring Systems Deep Dive
How 9-cat, 8-cat, points, and roto formats reshape who you should draft. Same player, four different values.
Format #1 — Standard 9-Cat Head-to-Head
9-cat head-to-head is the most common fantasy basketball format. Nine statistical categories. Win 5 of 9 each week, win the matchup.
The nine cats: PTS, REB, AST, STL, BLK, 3PM, FG%, FT%, TO. Eight count up. Turnovers count down. Your weekly matchup is nine separate races, one per category.
This format rewards well-rounded contributors. The Jokić, Luka, SGA archetype — guys who chip in across multiple categories — are gold. Specialists who pile up one or two categories at the expense of others can still work in a punt build, but require strategic roster construction.
Standout 2024-25 9-cat archetypes: Jokić (all-around), Wembanyama (defense + boards), Curry (3PM + FT% + assists), Tyrese Haliburton (assists + 3PM + FT% specialist).
Format #2 — Points Leagues
Points leagues sum everything into one number using a custom scoring formula. Easier to learn, but the strategy is completely different from 9-cat.
Standard points-league scoring: PTS=1, REB=1.2, AST=1.5, STL=3, BLK=3, 3PM=0.5, TO=-1. Some leagues add FG% bonus, FT% penalty, or weight categories differently.
The biggest shift from 9-cat: volume wins everything. Inefficient high-volume scorers (Trae Young, Devin Booker) gain value because shots missed don't hurt you the way they do in FG%. Conversely, efficient role players (Brook Lopez) lose value because their per-game total is lower.
Steals and blocks are weighted aggressively in points (3.0x). That makes defensive specialists who never start in 9-cat builds — your OG Anunoby, your Herb Jones — into starting-level pieces. A guard who averages 2.0 steals adds 6.0 points per game just on theft.
Format #3 — Roto and Hybrid Formats
Roto (rotisserie) leagues don't have weekly matchups. Instead, your season-long category totals are ranked against the league at the end, and you win points based on those rankings.
In a 12-team roto league, leading the league in a category earns 12 points; last place earns 1. Add up your 9 category scores. Highest sum wins.
Roto rewards balance and consistency. Punting works less well — being last in a punted category costs you 11 ranking points you can't make up. The best roto teams compete across all nine cats and lock in top-3 finishes in 5-6 of them.
Roto also makes the entire season the matchup. There's no week-to-week strategy. There's just the cumulative score climbing. Roto rewards healthy, consistent stars over high-ceiling injury cases.
Format #4 — Daily Fantasy and Best Ball
Daily fantasy (DFS) and best ball are different animals — single-game (DFS) or pre-draft locked (best ball) contests where you don't manage week-to-week.
DFS rewards optimization. You build a lineup against a salary cap, knowing every other player's projected output. The math is closer to poker than season-long fantasy. Edges come from injury news, vegas movement, weather (irrelevant for NBA), and pace-up matchups.
Best-ball drafts let you set a 25-30 round roster pre-season and then platform auto-optimizes your starting lineup every week. No waivers. No trades. Best-ball is the purest test of draft skill — you cannot fix a bad draft.
POSEIDON projections cover all four formats. The same player gets ranked differently in 9-cat vs points vs roto vs DFS — and we show you why, with the math.
