THE AVERAGE DYNASTY TRADE IS 40% LOPSIDED

We assigned FantasyCalc dynasty values to both sides of every trade in our 125,000+ Sleeper trade dataset. The finding: the average dynasty trade has a 40% value gap between sides. Here's why that matters — and why it's probably fine.

Mean Gap

Median Gap

Std Deviation

The median dynasty trade — the absolute midpoint of every deal in our dataset — has a 39.1% value gap between what Side A receives and what Side B receives. Half of all trades are more uneven than that. The mean is nearly identical at 40.3%, and the standard deviation is 24.2%, meaning the middle 68% of trades fall between about 16% and 64% gaps.

THE DISTRIBUTION: WHERE DOES YOUR TRADE FALL?

GapTier% of TradesWhat It Means
0–15%Fair / Close~35%Both sides getting reasonable value. Normal dynasty trade.
15–40%Slight–Clear Win~30%One side favored. Common when contenders pay premiums or rebuilders sell cheap. The median trade falls right here.
40–75%Lopsided~25%Meaningfully one-sided. Often explained by a rebuild strategy, a value misjudgment, or a player whose situation changed.
75–85%Very One-Sided~5%Top 10% of all trades. Worth a second look — but could easily be a legitimate rebuild dump.
85–96%Statistical Outlier~4%Top 5%. Unusual enough that most leagues would want context on why it happened.
96%+Extreme Outlier~1%Top 1%. In our data, these are almost always roster dumps from a manager quitting, or severe misjudgments.

WHY DYNASTY TRADES ARE NATURALLY UNEVEN

If every trade were perfectly "fair" by value, the average gap would be close to zero. It's not — it's 40%. The reason is that dynasty trades aren't supposed to be even. They're supposed to serve two different strategies at the same time:

  • Contenders pay premiums. A team pushing for a championship is willing to overpay in long-term value because a win this year is worth more to them than picks three seasons out.
  • Rebuilders sell below market. A rebuilding team moves veterans for pennies on the dollar because they want youth, picks, and flexibility — not win-now production.
  • Values are imperfect. FantasyCalc consensus values are the best available, but they don't capture injury risk, landing-spot upside, or league-specific scoring. A player worth 3,000 in one league might be worth 5,000 in another.
  • Not everyone checks value charts. Some managers trade on gut, name recognition, or personal preference. That's their right — and it's why a 40% gap is the norm, not the exception.

WHEN SHOULD A COMMISSIONER STEP IN?

A large value gap is a data point, not a verdict. Even the most lopsided trades in our dataset have innocent explanations. That said, the data gives commissioners a useful framework:

Under 75%:Let it go. This is well within the normal range of dynasty trading. Vetoing trades in this range is overreach.
75–85%:Worth asking "what's the context?" If both managers can explain their reasoning (rebuild, roster crunch, value disagreement), no action needed.
85%+:Flag for review. In our data, this level of imbalance usually has an explanation (manager quitting, panic sell), but it's unusual enough that the league deserves transparency on why.

The key question isn't "is this trade fair?" — it's "is this trade intentionally harmful to the league?" A manager dumping their roster to a friend is different from a rebuilder making a bad sell-low. The value gap is the same; the intent is not.
