Dynasty Age Cliff Report 2026
Exact age-decay curves used by the RosterOdds dynasty model
Published February 2026 ยท Citation-safe from FantasyHype projection model constants
Key Findings
- RB has the steepest dynasty decline: 10% per year after age 26.
- WR declines 6% per year after age 29.
- TE declines 5% per year after age 30.
- QB is the slowest-decay position: 4% per year after age 33.
Dynasty Age Curves by Position
These values come directly from the dynasty multiplier function in the RosterOdds trade model.
| Position | Peak Window | Decay Starts | Annual Decay | Model Note |
|---|---|---|---|---|
| QB | 26-33 | 34 | 4% | Longest stable dynasty runway. |
| RB | 22-26 | 27 | 10% | Fastest value drop once past peak. |
| WR | 23-29 | 30 | 6% | Moderate decline after prime window. |
| TE | 24-30 | 31 | 5% | Shallower decline than RB/WR. |
Decay Math (Using Model Constants)
For players above the peak window, dynasty multiplier follows: 1.0 - (age - peakEnd) * decayRate, with a minimum floor of 0.40.
Example from the model: an RB at age 29 is 3 years beyond peak end (26), so multiplier is 1.0 - (3 * 0.10) = 0.70 before other adjustments.
Youth premium is also model-defined: players younger than each position's peak start receive +2% per year below that threshold.
Practical Draft/Trade Use
RB: treat post-26 backs as shorter-horizon assets in dynasty negotiations.
WR/TE: prime windows are longer, so dynasty hold windows can be wider.
QB: slow decay supports longer-term roster stability and less forced churn.
