We Backtested Every Preseason RB1 Pick from 2019–2024 — Here's the Hit Rate

A six-season backtest of preseason RB1 ADP versus end-of-season fantasy finishes. The Sharksnip model breaks down which RB profiles hit and which crater.

We get asked the same question every August: can I trust the consensus RB1? Last year's RB1 is going off the board first, and the takes are everywhere about whether he repeats. So we ran the actual numbers. Six seasons (2019 through 2024), every preseason RB drafted as a top-12 RB, scored on whether they finished as a top-12 RB at season's end. The hit rate is uglier than most people remember, and the patterns are repeatable.

The headline number

Across 2019–2024, of the 72 preseason top-12 RB selections, 38% hit RB1 finishes. That is roughly the same hit rate as flipping a coin and getting tails. The "elite" tier (top-5 RB ADP) hit at 46%. The back half of the RB1 ADP tier (RB7–RB12) hit at 30%.

For comparison, top-12 preseason WR ADPs hit at about 52% over the same window. WRs are simply more predictable.

What separates the hits from the misses

This is where the backtest gets interesting. Of the 27 RB1 ADP backs who hit, the model can retroactively classify them by three preseason features:

  1. Snap share over 70% in the prior season — 21 of 27 hits had this feature.
  2. No major injury history (no missed games for 2 consecutive years) — 19 of 27 hits.
  3. Stable coaching staff (same OC entering the season) — 23 of 27 hits.

An RB drafted in the top-12 with all three traits hit RB1 at roughly 60%. An RB drafted in the same range with two or fewer of those traits hit at roughly 24%. That gap is the entire ballgame in early drafts.

The miss profiles

Of the 45 misses, three patterns dominate:

1. Age-29-and-up backs coming off a top-5 finish

14 of these in the sample. Hit rate: 21%. Consensus prices them as if last year's finish is repeatable. The body says otherwise. We covered this in the RB regression piece — TD luck doesn't survive a year, and snap share starts eroding faster after 28.

2. Backs whose team changed offensive coordinators

11 of these in the sample. Hit rate: 27%. A new OC means usage uncertainty, and consensus assumes "elite talent overcomes scheme" until proven otherwise. The data doesn't back that up. New coordinators meaningfully reshape RB usage, and that almost always means a tier drop in a back's first year under them.

3. RBs entering season as the assumed lead in a committee

9 of these in the sample. Hit rate: 22%. If you have to read tea leaves about whether a back is "the guy" in his backfield, he probably isn't going to be a workhorse, and committees rarely produce RB1 finishes.

Combine those three buckets and you have 34 of 45 misses — about 75% of preseason RB1 busts come from these archetypes. Avoiding them is one of the cleanest structural edges in fantasy drafting.

What about the late-round RB hits?

The flip side of the same backtest: how many top-12 fantasy RB finishes came from outside the preseason RB1 tier? About 45%. That is the structural argument for late-round RB strategy. Almost half of every season's RB1 finishes come from backs who were drafted in Round 5+, often via mid-season injuries, role expansions, or breakout years.

Of those late-round RB1 finishes, the most common preseason features were:

  • Backup RB on a team with an injury-prone starter (handcuff value cashing in).
  • Year-2 RB drafted between RB30 and RB45 after a clean rookie year with rising snap share.
  • Free-agent or trade-acquired RB joining a top-12 offense by team total with no incumbent starter.

This is exactly the type of pattern surfaced by the model in the ADP value tiers piece as Zone 4 sleepers. The hit rate per individual late pick is low, but the cost is so low that you can stack 4 or 5 of them in a draft and one or two will pop.

The implication for draft strategy

Three takeaways from the backtest that should change how you draft:

Don't pay full price for RB7–RB12 ADP

This is the highest-bust zone in the entire draft. 30% RB1 hit rate at top-12 ADP, with all the downside of a Round 2 sin cost. The model consistently fades this tier in favor of WR or TE depth, then circles back to RB in Round 5+.

Pay more for RB1–RB5 ADP if they have all three "stable" features

60% hit rate is fantasy gold. If a top-5 RB has stable coaching, no injury history, and a 70%+ prior snap share, his ADP is fair or even slightly cheap.

Hammer Round 6+ RB depth

Don't roster two RBs and call it a day. Roster four or five from the late-round handcuff and year-2 archetypes. Use the draft kit to identify which late-round backs match the historical hit profile.

Caveats on the backtest

A few honest disclosures:

  • Sample size. 72 preseason RB1 picks across six seasons is a real sample but not a huge one. Confidence intervals on the bucket-level hit rates are wide; treat the 21% / 27% / 22% miss profiles as directional, not surgical.
  • Survivor bias on hits. The "all three stable features" hit rate of 60% is real, but the underlying back is also drafted at a higher cost. The expected fantasy points relative to ADP isn't always better — it's just safer.
  • 2020 was a weird year. COVID protocols affected snap share data and we noted the year as an outlier in the model. Removing 2020 entirely shifts the hit rate by less than 2 percentage points, so the conclusions hold.

Bottom line

Preseason RB1 ADP is a 38% hit rate market priced like a 60% hit rate market. The hit profile is highly predictable — stable coaching, no recent injuries, prior 70%+ snap share. The miss profile is just as predictable, dominated by aging veterans, new coordinators, and committee leads. Avoid the miss profile, pay up for the hit profile, and stack late-round RB depth where almost half of all RB1 finishes actually come from.
