Risk and opportunity flags

Top three concerns and top two upside signals from the model.

Duke Johnson
Risks
  • Not on any consensus board
    Model has him at pick #62 but ZERO public big boards have him on their list. Either we're seeing something nobody else does, or the model is hallucinating.
Opportunities
No standout upside flags.
David Cobb
Risks
  • One-year wonder
    Production concentrated in one season: best 1629 rushing yards vs 4-season mean 724. Limited multi-year tape — small sample of true production.
  • Negative per-play impact
    PPA avg_all 0.132 — per-snap contribution is below-average for the position. Volume stats overstate the impact.
Opportunities
No standout upside flags.
Todd Gurley
Risks
  • Not on any consensus board
    Model has him at pick #29 but ZERO public big boards have him on their list. Either we're seeing something nobody else does, or the model is hallucinating.

David Cobb

Production concentrated in one season: best 1629 rushing yards vs 4-season mean 724. Limited multi-year tape — small sample of true production. The call is a hold: no public board ranks him, so the model's #118 stands alone — and with bust risk at 6%, let the room catch up before paying a premium.

Todd Gurley

Draftanomics projects Todd Gurley (age 20.7 at draft) as a first-round pick at #29 (range #15-#43, wide band). Bust probability sits at 0% — low. The call is a hold: no public board ranks him, so the model's #29 stands alone — and with bust risk at 0%, let the room catch up before paying a premium.
