Risk and opportunity flags

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

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.
Josh Robinson
Risks
  • No athletic testing
    No Combine drills or Pro Day numbers on file while most of the class has tested — the athletic part of the grade is unmeasured.
  • Negative per-play impact
    PPA avg_all 0.255 — per-snap contribution is below-average for the position. Volume stats overstate the impact.
Opportunities
  • Breakout production arc
    Career trajectory in rushing yards: 335 → 459 → 1203. Production rose every season — the kind of upward arc that often continues into the league.

Verdict

The model's plain-English read.

David Cobb

Draftanomics projects David Cobb (age 21.9 at draft) as a mid-round flyer at #118 (range #116-#120, tight projection). Bust probability sits at 6% — low. 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.

Josh Robinson

Draftanomics projects Josh Robinson (age 22.7 at draft) as a Day 3 dart throw at #245 (range #243-#247, tight projection). Bust probability sits at 77% — scary. Career trajectory in rushing yards: 335 → 459 → 1203. Production rose every season — the kind of upward arc that often continues into the league. No Combine drills or Pro Day numbers on file while most of the class has tested — the athletic part of the grade is unmeasured. The call is a hold: no public board ranks him, so the model's #245 stands alone — and with bust risk at 77%, let the room catch up before paying a premium.
