Commissioner Flex Scoring: How Fantasy Football Commissioners Set Up Flex Scoring Positions
Standard FLEX configurations: the most common FLEX configurations in fantasy football leagues are (1) RB/WR/TE FLEX — the most standard, allowing any skill position to fill the FLEX slot; (2) WR/TE only FLEX — narrows the FLEX to pass-catchers, increasing TE value and reducing WR depth requirements; (3) RB/WR only FLEX — excludes TEs from the FLEX, keeping TE a pure standalone position; (4) QB/WR/RB/TE FLEX (superflex) — allows any skill position including QB, dramatically increasing QB value and scarcity. Each configuration creates a different set of positional values and draft priorities.
FLEX Configuration Quick Reference
| FLEX type | Who benefits most | Draft adjustment | Mistake to avoid |
|---|---|---|---|
| RB/WR/TE FLEX (standard) | All skill positions compete for FLEX — best available player fills it | Draft ~3 RBs, 4–5 WRs, 1–2 TEs to have FLEX options | Ignoring depth at all three positions — in standard FLEX, the 3rd RB, 5th WR, and 2nd TE are all legitimate weekly starters |
| WR/TE only FLEX | WRs and TEs — increased demand for both, especially TEs | Elite TEs rise 1–2 rounds vs. standard; WR3 depth becomes more valuable | Treating this like standard FLEX and ignoring the TE premium — WR/TE only FLEX makes elite TEs scarcer than standard |
| RB/WR only FLEX | RBs and WRs — TEs reduced to single-starter necessity | TE falls 1–2 rounds vs. standard; invest FLEX rounds in RB/WR depth | Over-investing in TE in a RB/WR only FLEX league — the TE has one dedicated slot; depth beyond TE1 has no FLEX value |
| Superflex (QB included in FLEX) | QBs — all 24 starters in a 12-team league need 2 QBs each | Take QBs in rounds 1–3; positional value inverts vs. standard — QB is the scarce position | Single-QB draft approach in a superflex league — you will not get a viable QB2 by the time you need one |
| Two FLEX slots | Depth players — 3rd RBs, 5th WRs, and 2nd TEs become legitimate weekly starters | Value extends 1–2 extra rounds at each skill position vs. single FLEX | Drafting only enough for single-FLEX coverage — the second FLEX means your 6th and 7th WRs have real starter weeks |
| IDP FLEX (individual defensive players in FLEX) | Defensive players — LBs, DBs, and DLs compete for FLEX | Draft IDP starters by round 8–10 to cover both sides of the FLEX | Ignoring IDP until late rounds in an IDP FLEX league — top IDP players get taken earlier than standard because they fill a FLEX slot |
How FLEX Changes Draft Strategy
RB/WR/TE FLEX. In a standard RB/WR/TE FLEX league, the FLEX slot creates an additional starting position for whichever skill position has the best available player in any given week. This puts a slight premium on depth across all three positions and makes late-round picks at RB, WR, and TE more valuable because they compete for the FLEX slot. Managers need approximately 3 RBs, 4–5 WRs, and 1–2 TEs to have competition for the FLEX slot.
Superflex impact on QB. When the FLEX can be filled by a QB (superflex format), the entire draft board shifts toward QBs. In a 12-team superflex league, 24 QBs are needed as starters each week — more than the number of truly elite NFL QBs. This creates QB scarcity that does not exist in single-QB formats, pushing elite QBs into rounds 1–2 and reshaping all subsequent picks.
Multiple FLEX Slots
Two FLEX vs. one FLEX. Some leagues use two FLEX positions instead of one. The second FLEX creates additional starting spots for depth players and rewards managers who drafted well beyond their starting lineup. Two-FLEX leagues increase the value of the 3rd RB, 5th WR, and 2nd TE on rosters because these players now compete for starter positions more often.
