Nobody has answered this question with real data. Until now.
Every dynasty fantasy football player faces the same moment in their rookie draft: it’s round 3, you need weapons on offense, but there’s a linebacker sitting there that your gut says is undervalued. Do you take him?
The fantasy football community has debated this for years based on gut feel, anecdotal evidence, and recycled opinions. At IDPInsider, we decided to actually answer it with data.
We analyzed 6 rookie drafts across 2 leagues over 3 years (2023, 2024, 2025) — tracking every pick, every player’s final season scoring output, and comparing IDP assets directly against their offensive counterparts. One league uses tackle-heavy scoring (The Gridiron Syndicate). The other rewards big plays, interceptions, and pass rushers at a premium (DC vs Marvel). There’s an additional wrinkle: the DC vs Marvel league conducts its rookie draft before the NFL Draft — meaning managers select IDP assets without knowing landing spots, depth charts, or defensive schemes. Combined, we tracked over 90 rookie draft picks and their actual fantasy production.
Here is what the data shows.
The Setup: Two Leagues, Two Scoring Systems
Before we get into the findings, understanding the scoring differences matters because they change everything about which IDP positions to target — even if they don’t change when to target them.
The Gridiron Syndicate (tackle-heavy scoring):
- Tackles: 1 point each
- Assists: 0.5 points
- Sacks: 5 points
- Interceptions: 2 points
- Passes Defended: 1 point
- Forced Fumbles: 6 points
DC vs Marvel (big play scoring):
- Tackles: 2 points each (double)
- Assists: 1 point
- Sacks: 6 points
- Interceptions: 6 points (triple)
- Passes Defended: 3 points (triple)
- QB Hits: 1 point
- DT Tackles: 3.5 points (position-specific bonus)
The DC vs Marvel format rewards playmakers — ball hawks, pass rushers, and big hitters. The Gridiron Syndicate format rewards volume — the guys who show up every Sunday and rack up tackles.
Same positions, completely different value hierarchy. So how does that affect when you should be drafting IDP? Let’s look at the data.
Finding #1: Rounds 3-5 Are the IDP Value Window — In Both Leagues
This is the headline finding. Across both leagues, across all three years, IDP assets taken in rounds 3 through 5 consistently match or outperform offensive picks selected in the same rounds.
Gridiron Syndicate — Average Points by Round:
| Round | Offense Avg | IDP Avg | Winner |
|---|---|---|---|
| Round 1 | 221 pts | No IDP taken | Offense |
| Round 2 | 179 pts | 101 pts | Offense |
| Round 3 | 107 pts | 116 pts | IDP |
| Round 4 | 153 pts | 115 pts | Offense (narrow) |
| Round 5 | 63 pts | 128 pts | IDP by 2x |
DC vs Marvel — Average Points by Round:
| Round | Offense Avg | IDP Avg | Winner |
|---|---|---|---|
| Round 1 | 358 pts | No IDP taken | Offense |
| Round 2 | 310 pts | 267 pts | Offense (narrow) |
| Round 3 | 180 pts | 245 pts | IDP by 36% |
| Round 4 | 290 pts | 209 pts | Offense |
| Round 5 | 190 pts | 200 pts | IDP |
The pattern is consistent across both formats: don’t reach for IDP in rounds 1-2, but from round 3 onward the value is there — and sometimes it absolutely obliterates the offensive alternatives.
Finding #2: The Outlier Effect Is Real and It’s IDP
The most compelling argument for drafting IDP in rounds 3-5 isn’t the averages — it’s the ceiling. Offensive players in rounds 3-5 rarely produce like round 1 picks. But IDP players in rounds 3-5 do it regularly.
The best examples from our data:
Carson Schwesinger, LB — Gridiron Syndicate 2025 Drafted at pick 4.07. Scored 266.5 points on the season. That output would have ranked him as the #4 offensive rookie overall — behind only Ashton Jeanty (1.01), TreVeyon Henderson (1.07), and Jaxson Dart (1.08). He outscored the 1.04 pick, Tetairoa McMillan, by 46 points. From 3 rounds later.
Devon Witherspoon, CB — Both leagues 2023 In the Gridiron Syndicate, Witherspoon was taken at pick 5.09 and scored 205 points — the highest IDP rookie total that year. In DC vs Marvel, he was taken even later at 6.05 and scored 267 points in the big play format where interceptions and passes defended earn premium points. In both leagues, from both late-round picks, he was an elite fantasy asset.
Edgerrin Cooper, LB — Gridiron Syndicate 2024 Taken at 3.08, Cooper scored 197.5 points — ranking him among the top offensive rookies from rounds 1 and 2. The manager who drafted him got round 1 value from a round 3 pick.
Nick Emmanwori, S — Gridiron Syndicate 2025 Taken at 4.10, Emmanwori scored 189.5 points — which would have ranked him #10 among all offensive rookies. Taken in round 4.
This pattern repeats year after year. The IDP outlier in rounds 3-5 is not a fluke. It’s a structural feature of how defensive players are undervalued in dynasty rookie drafts.
Finding #3: Your Scoring Format Changes the Position — Not the Round
Here is the most actionable finding in this entire dataset.
Both leagues confirm the same round window (3-5) for IDP value. But the scoring format dramatically changes which positions deliver that value.
In tackle-heavy scoring (Gridiron Syndicate style):
Linebackers are the foundation. The three-down linebacker who plays 95% of snaps and racks up 100+ tackles is your single most reliable IDP asset. In our data, LBs accounted for the top 5 IDP rookie performances in tackle-heavy scoring across three years. Draft LBs aggressively in rounds 3-4.
Safeties are the sleeper. Box safeties who produce tackle volume are consistently undervalued. Emmanwori and Starks in 2025, Battle in 2023 — all produced elite numbers from round 4-5 picks.
Avoid DTs. In tackle-heavy scoring without position-specific bonuses, DTs simply do not produce enough points. Our data shows DTs averaging only 61.5 points in the Gridiron Syndicate format. Unless your league has DT-specific bonuses, deprioritize them entirely in rookie drafts.
In big play scoring (DC vs Marvel style):
CBs are the hidden gem. With interceptions worth 6 points and passes defended worth 3 points, ball-hawk cornerbacks become elite fantasy assets. Witherspoon (267 pts), Sainristil (248.5 pts), and DeJean (121.94 pts as a rookie) all show what happens when a coverage corner hits in a premium scoring format. Draft CBs earlier than your peers in big play leagues.
DTs are viable. The position-specific tackle bonus (3.5 pts per tackle for DTs in DC vs Marvel) combined with QB hits makes penetrating interior linemen productive. Turner scored 265.5 points as an undrafted DT in 2023. This position is regularly available in rounds 4-6 at significant discount.
Safeties remain strong. The high interception value makes playmaking safeties elite in big play formats — Nubin (196.5 pts as a rookie), Branch (231 pts), and others confirm this year after year.
Finding #4: Round 2 IDP Is Usually a Trap
Managers who reach for IDP in round 2 consistently get burned. Our data shows round 2 offensive averages of 179-310 points per league, while round 2 IDP averages 101-267 points. The top end of round 2 IDP (Abdul Carter, Will Anderson) produces — but the floor is much lower than offense at that range.
The one exception: in big play scoring leagues, if a premier pass rusher or ball-hawk CB falls to late round 2, the upside matches offense. But as a general rule, let round 2 be offensive.
The Framework: When to Pull the IDP Trigger
Based on three years of real data across two leagues, here is the actionable draft framework:
Rounds 1-2: Build your offensive core. The data is clear — elite offensive rookies outperform IDP in rounds 1-2. Take your franchise QB, elite RB, or top WR. Let IDP go.
Round 3: IDP becomes equal value. In our data, round 3 IDP averages match or beat round 3 offense. This is where you can take your first IDP asset without sacrificing value. Target: three-down LBs in tackle leagues, premier pass rushers or versatile CBs in big play leagues.
Rounds 4-5: IDP is often the better pick. The offensive hit rate drops sharply in rounds 4-5 while IDP continues to produce. Schwesinger, Emmanwori, Witherspoon, Cooper — the biggest IDP value picks in our dataset almost all came from rounds 4-5. This is where you gain real draft edge over managers who ignore IDP.
Rounds 6+: Target your format’s sleeper position. In big play leagues, undrafted DTs and backup CBs with starting upside are gold. In tackle leagues, backup LBs one injury away from a starting role have massive upside.
The Position Priority List by Format
Tackle-Heavy Scoring (1pt tackles, 5pt sacks):
- Three-down linebacker
- Box safety
- Edge rusher with pass rush role
- CB2 with upside
- DT (deprioritize unless elite)
Big Play Scoring (2pt tackles, 6pt INTs, 3pt PDs):
- Ball-hawk cornerback
- Playmaking safety
- Premier pass rusher
- Three-down linebacker
- Interior DT with penetration role
Finding #5: The Pre-NFL Draft Variable — And Why It Makes IDP Even More Impressive
There is one critical detail about the DC vs Marvel league that makes its findings even more compelling: their rookie draft takes place before the NFL Draft.
That means managers are selecting IDP assets without knowing where those players will land. A linebacker could end up on a run-stuffing defense that keeps him on the field 90% of snaps — or he could land behind an established veteran with a limited role. A cornerback could go to a team that gets torched weekly, generating tons of INT and PD opportunities — or he could sit as a backup on a dominant secondary.
The uncertainty is enormous. And yet IDP still delivered value in rounds 3-5 in the DC vs Marvel league across all three years.
This actually strengthens the core finding of this article. If IDP assets produce consistent value even when drafted under maximum uncertainty — before landing spots, depth charts, or defensive schemes are known — then the value window is even more reliable in post-NFL Draft leagues where you have full information.
What changes in pre-NFL Draft leagues:
The positions that carry the least pre-draft risk are the safest IDP targets. Three-down linebackers and box safeties produce tackle volume regardless of scheme — a high-usage LB generates points whether his team runs a 4-3 or 3-4. This makes volume-based IDP positions safer pre-draft picks than big play positions.
Cornerbacks and pass rushers carry more pre-draft risk because their value is heavily dependent on role and scheme fit. A CB1 on a zone-heavy team generates fewer INTs and PDs than a press corner on an aggressive defense. A pass rusher in a two-gap scheme generates fewer sacks than one in an attacking scheme.
The pre-draft IDP priority adjustment:
In post-NFL Draft leagues, all IDP positions in rounds 3-5 are viable based on the framework above. In pre-NFL Draft leagues, weight your picks toward volume-based positions first:
- Three-down linebacker (scheme-independent tackle volume)
- Box safety (consistent volume regardless of scheme)
- Edge rusher with clear pass rush designation (higher pre-draft certainty)
- CB1 candidate at a team with known coverage needs (more risk, higher ceiling)
The DC vs Marvel data proves that even pre-draft IDP picks in rounds 3-5 produce. With the additional information available in post-draft leagues, the value window only gets stronger.
Conclusion
The fantasy football community has been guessing about IDP draft value for years. The data from two real leagues over three years gives us a clear answer:
Draft IDP starting in round 3. Target LBs first in tackle leagues, CBs first in big play leagues. Expect your best value in rounds 4-5 where the IDP outlier effect is strongest. Avoid reaching in rounds 1-2.
The managers in our leagues who follow this framework consistently get round 1-2 value from round 3-5 picks. The managers who ignore IDP until the final rounds miss the window entirely.
Now you have the data. Use it.
