Your dynasty league's offseason isn't downtime—it's when championships are built. We analyzed 2.2 million roster-seasons to prove it.
The Offseason Is the Main Event
If you think dynasty fantasy football is won on Sunday afternoons, the data says otherwise. Across 2.2 million roster-seasons, a staggering two-thirds of all dynasty trades happen before Week 1. The offseason is not the intermission—it's the main event. And how you use it determines whether you're raising a trophy or rebuilding again next year.
But here's the twist: it's not just about trading more in the offseason. Winners distinguish themselves by being active in every window—offseason, in-season, and especially at the trade deadline. Let's break down exactly what the data shows.
Winners Trade More—Everywhere
Winners
trades per season
66.1% offseason / 33.9% in-season
Non-Winners
trades per season
66.9% offseason / 33.1% in-season
Key Insight
Winners don't just trade more in the offseason—they trade 9% more in-season than non-winners (1.16 vs 1.06). The biggest edge isn't about when you trade, it's about being active in every trading window.
The Standing Ladder: Trade Volume by Finish
The relationship between trading activity and final standing reveals a fascinating pattern. The top finishers and bottom finishers both trade aggressively—but for very different reasons. The middle of the pack? That's where activity flatlines.
The U-Shaped Curve
Notice the U-shape: 1st place averages 3.43 trades, the middle (6th-7th) drops to 2.88, and then last place surges to 4.73. Top teams trade aggressively to win. Last place teams trade aggressively to rebuild. The danger zone is the mushy middle—teams that aren't trading enough to contend or rebuild.
The Bounce-Back: Trading After a Losing Season
This is the most actionable finding in the entire study. If you finished in the bottom half last year, how many offseason trades you make directly predicts your odds of bouncing back.

The Trade Deadline Edge
Among teams that are active in-season, winners concentrate more of their activity around the trade deadline (weeks 9-13), the critical window where contenders make their push.

Format Matters: Superflex vs 1QB
Superflex leagues generate more trading activity across the board. The extra QB value creates additional trade leverage and more paths to roster improvement.
1QB Leagues
Superflex Leagues
The winner edge is larger in 1QB (7.2% vs 5.2%), though both formats show a clear advantage for active traders.
What This All Means
The Offseason Window
Two-thirds of all dynasty trades happen before Week 1. If you're not active in the offseason, you're missing the majority of the market.
The Bounce-Back Effect
Bottom-half teams that made 3-5 offseason trades improved by 2.2 positions on average. Active rebuilding works.
The In-Season Edge
Winners make 9% more in-season trades than non-winners. They don't stop at the offseason—they stay active through the deadline.
The data is clear: the offseason is the most important time to trade in dynasty fantasy football. It's where the majority of deals happen, it's where rebuilding teams make their comebacks, and it's where winners start building their championship rosters. But the best managers don't stop there—they maintain their edge by staying active in-season and making targeted moves at the trade deadline.
If you're reading this in the offseason, you're in the most valuable trading window of the year. Every week that passes without a deal is a missed opportunity to reshape your roster.
