Nobody has answered this question with real data. Until now.
IDP fantasy football is one of the most exciting formats in the game — and if you play dynasty, the rookie draft is where leagues are won and lost. Every manager faces the same moment: it’s round 3 or 4, you need offensive weapons, but there’s a linebacker or safety 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 real data.
We analyzed 15 rookie drafts across 2 leagues spanning 9 years (2017-2025) — 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, active since 2017). The other rewards big plays, interceptions, and pass rushers at a premium (DC vs Marvel, active since 2020). 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 200 rookie draft picks and their actual fantasy production across nearly a decade.
Here is what the data shows.
The Setup: Two Leagues, Two Scoring Systems, Nine Years
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. Nine years of data to back it up.
Finding #1: Rounds 3-5 Are the IDP Value Window — Every Single Year
This is the headline finding. Across both leagues, across all nine years, IDP assets taken in rounds 3 through 5 consistently match or outperform offensive picks selected in the same rounds.
This is not a fluke. It is not a three year sample size quirk. It is a structural feature of how dynasty managers value defensive players — and it has repeated itself every single year in our data.
Gridiron Syndicate — Average Points by Round (2023-2025):
| 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 (2023-2025):
| 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 holds across both formats: avoid reaching for IDP in rounds 1-2, but from round 3 onward the value is consistently there — and in rounds 4-5, IDP regularly demolishes the offensive competition.
Finding #2: The Hall of Fame IDP Value Picks — 9 Years of Evidence
The most compelling argument for drafting IDP in rounds 3-5 is not the averages — it’s the ceiling plays. These are the picks that prove the outlier effect is real, repeatable, and format-independent.
Darius Leonard, LB — Gridiron Syndicate 2018 — Pick 5.09
The single most dramatic example in nine years of data. Leonard was taken at pick 5.09 — the second-to-last pick of the draft. He went on to score 320 points, making him the #1 IDP scorer that entire season. From the last round of the rookie draft. This is not an anomaly — it is proof that IDP value goes undrafted every single year.
Minkah Fitzpatrick, S — Gridiron Syndicate 2018 — Pick 3.01
Fitzpatrick was taken at 3.01 and scored 280 points — production that would have rivaled round 1 offensive picks in any format. Safety value from a round 3 pick is exactly what the data predicts.
T.J. Watt, LB — Gridiron Syndicate 2017 — Pick 3.08
Watt went at 3.08 in the very first year of our dataset and scored elite numbers. The pattern started from year one and has never stopped.
Carson Schwesinger, LB — Gridiron Syndicate 2025 — Pick 4.07
Schwesinger was taken at pick 4.07 and scored 266.5 points — which would have ranked him #4 among ALL offensive rookies, behind only Ashton Jeanty (1.01), TreVeyon Henderson (1.07), and Jaxson Dart (1.08). He outscored the 1.04 pick by 46 points. From three rounds later.
Devon Witherspoon, CB — Both Leagues 2023
In the Gridiron Syndicate, Witherspoon was taken at pick 5.09 and scored 205 points. In DC vs Marvel, he was taken even later at 6.05 and scored 267 points in the premium scoring format. In both leagues, from late round picks, he was an elite fantasy asset.
Edgerrin Cooper, LB — Gridiron Syndicate 2024 — Pick 3.08
Cooper scored 197.5 points from pick 3.08 — ranking among the top offensive rookies from rounds 1 and 2.
Aidan Hutchinson, DE — Gridiron Syndicate 2022 — Pick 3.04
Hutchinson scored 265 points from pick 3.04, delivering round 1 offensive value from round 3.
Marshon Lattimore, CB — Gridiron Syndicate 2017 — Pick 5.01
Lattimore scored 217 points from pick 5.01 in year one of the dataset. The trend started immediately and has never reversed.
Nine years. Two leagues. The story is the same every time.
Finding #3: Your Scoring Format Changes the Position — Not the Round
Here is the most actionable finding in the 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, the top IDP performances in tackle-heavy scoring across nine years are dominated by linebackers — Schwesinger, Cooper, Leonard, Watt, Smith, Campbell. Draft LBs aggressively in rounds 3-4.
Safeties are the sleeper. Box safeties who produce tackle volume are consistently undervalued. Fitzpatrick, Adams, Emmanwori, Starks, Battle — all produced elite numbers from round 3-5 picks. The safety position is where you find the second wave of IDP value.
Avoid DTs. In tackle-heavy scoring without position-specific bonuses, DTs simply do not produce enough points. 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), Lattimore (217 pts) — ball-hawking CBs in premium formats are genuinely first-round caliber assets available in rounds 5-6. Draft them earlier than your peers every single year.
DTs are viable. The position-specific tackle bonus 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 in both formats. The high interception value makes playmaking safeties elite in big play formats. Fitzpatrick, James, Branch, Nubin — the safety position produces across scoring systems year after year.
Finding #4: Round 2 IDP Is Almost Always a Trap
Nine years of data shows one consistent warning: reaching for IDP in round 2 almost never works out the way managers expect.
Round 2 offensive averages consistently run 179-310 points depending on the year and format. Round 2 IDP averages lag significantly. The top end of round 2 IDP — Nick Bosa, Chase Young, Abdul Carter — produces, but the floor is dramatically lower than offense at that range.
In 2018, Bradley Chubb went at 1.06 and disappointed relative to expectation. In 2020, Chase Young at 2.09 in DC vs Marvel was one of the rare round 2 IDP successes. In 2019, Nick Bosa at 2.01 was the exception that proves the rule.
The one exception to this rule: in big play scoring leagues, if a premier pass rusher or ball-hawk CB slides to late round 2, the upside can match offense. But as a general rule, let round 2 be offensive. The data across nine years supports this conclusion clearly.
Finding #5: The Pre-NFL Draft Variable
One critical detail about the DC vs Marvel league makes its findings even more compelling: their rookie draft takes place before the NFL Draft.
That means managers select IDP assets without knowing where players will land. A linebacker could end up in a run-stuffing scheme that maximizes his value — or sit behind a veteran with a limited role. A cornerback could land at a team that gets torched weekly — or back up a Pro Bowler 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 six years we tracked.
This strengthens the core finding. If IDP assets produce consistent value under maximum uncertainty — before landing spots, depth charts, or schemes are known — then the value window is even more reliable in post-NFL Draft leagues where you have complete information.
Pre-draft IDP position priority adjustment:
- Three-down linebacker (scheme-independent tackle volume)
- Box safety (consistent volume regardless of scheme)
- Edge rusher with clear pass rush designation
- CB1 candidate at a team with known coverage needs
The Complete Draft Framework: 9 Years Proven
Based on nine years of real data across two leagues, here is the actionable framework:
Rounds 1-2: Build your offensive core. Elite offensive rookies dominate rounds 1-2 in both leagues across all nine years. Take your franchise QB, elite RB, or top WR. Let IDP go.
Round 3: IDP becomes equal value. In our full dataset, round 3 IDP averages match or beat round 3 offense. This is where you take your first IDP asset without sacrificing value. Target: three-down LBs in tackle leagues, premier pass rushers or CBs in big play leagues.
Rounds 4-5: IDP is consistently the better pick. The offensive hit rate drops sharply while IDP continues to produce. Leonard, Schwesinger, Emmanwori, Witherspoon, Lattimore, Watt — the biggest IDP value picks in nine years almost all came from rounds 4-5. This is where you gain real draft edge.
Round 6+: Target your format’s sleeper position. In big play leagues, undrafted DTs and backup CBs with starting upside. In tackle leagues, backup LBs one injury from a starting role.
The Position Priority List by Format
Tackle-Heavy Scoring (1pt tackles, 5pt sacks):
- Three-down linebacker
- Box safety
- Edge rusher with pass rush role
- CB1 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
Nine Years. One Conclusion.
The fantasy football community has been guessing about IDP draft value for years. Nine years of data from two real leagues gives us a definitive 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 and most consistent. 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. Darius Leonard at 5.09. T.J. Watt at 3.08. Minkah Fitzpatrick at 3.01. Carson Schwesinger at 4.07. Devon Witherspoon at 5.09. Nine years of proof that IDP value is available late in every dynasty rookie draft.
Now you have the data. Use it.
