Risk and opportunity flags

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

Jay Ajayi
Risks
  • Not on any consensus board
    Model has him at pick #64 but ZERO public big boards have him on their list. Either we're seeing something nobody else does, or the model is hallucinating.
  • Negative per-play impact
    PPA avg_all 0.276 — per-snap contribution is below-average for the position. Volume stats overstate the impact.
Opportunities
  • Breakout production arc
    Career trajectory in rushing yards: 548 → 1425 → 1823. Production rose every season — the kind of upward arc that often continues into the league.

  • Breakout production arc
    Career trajectory in rushing yards: 225 → 958 → 2036. Production rose every season — the kind of upward arc that often continues into the league.

Verdict

The model's plain-English read.

Jay Ajayi

Draftanomics projects Jay Ajayi (age 21.9 at draft) as a Day 2 pick at #64 (range #62-#66, tight projection). Bust probability sits at 6% — low. Career trajectory in rushing yards: 548 → 1425 → 1823. Production rose every season — the kind of upward arc that often continues into the league. PPA avg_all 0.276 — per-snap contribution is below-average for the position. Volume stats overstate the impact. The call is a hold: no public board ranks him, so the model's #64 stands alone — and with bust risk at 6%, let the room catch up before paying a premium.

Tevin Coleman

Draftanomics projects Tevin Coleman (age 22.0 at draft) as a third-round / early Day 3 pick at #66 (range #64-#68, tight projection). Bust probability sits at 5% — low. Career trajectory in rushing yards: 225 → 958 → 2036. Production rose every season — the kind of upward arc that often continues into the league. PPA avg_all 0.220 — per-snap contribution is below-average for the position. Volume stats overstate the impact. The call is a hold: no public board ranks him, so the model's #66 stands alone — and with bust risk at 5%, let the room catch up before paying a premium.
