Risk and opportunity flags

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

Kaelin Clay
Risks
  • Older prospect
    Age 23.3 at draft. Slightly older than the cohort median (~22.5); upside ceiling is trimmed.
  • Negative per-play impact
    PPA avg_all 0.256 — per-snap contribution is below-average for the position. Volume stats overstate the impact.
Opportunities
No standout upside flags.
Evan Spencer
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.
  • Below-cohort college production
    Position-cohort z-score on production composite is -1.83 — well below the skill average. Raw box-score output didn't keep pace with peers.
  • Negative per-play impact
    PPA avg_all 0.227 — per-snap contribution is below-average for the position. Volume stats overstate the impact.
Opportunities
No standout upside flags.
JJ Nelson
Risks
  • Older prospect
    Age 23.0 at draft. Slightly older than the cohort median (~22.5); upside ceiling is trimmed.
  • 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.

Verdict

The model's plain-English read.

Kaelin Clay

Draftanomics projects Kaelin Clay (age 23.3 at draft) as a Day 3 dart throw at #228 (range #226-#230, tight projection). Bust probability sits at 71% — scary. Age 23.3 at draft. Slightly older than the cohort median (~22.5); upside ceiling is trimmed. The call is a hold: no public board ranks him, so the model's #228 stands alone — and with bust risk at 71%, let the room catch up before paying a premium.

Evan Spencer

Draftanomics projects Evan Spencer (age 21.9 at draft) as a Day 3 dart throw at #195 (range #193-#197, tight projection). Bust probability sits at 0% — low. 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 #195 stands alone — and with bust risk at 0%, let the room catch up before paying a premium.

JJ Nelson

Draftanomics projects JJ Nelson (age 23.0 at draft) as a Day 3 dart throw at #182 (range #161-#203, wide band). Bust probability sits at 18% — manageable. Age 23.0 at draft. Slightly older than the cohort median (~22.5); upside ceiling is trimmed. The call is a hold: no public board ranks him, so the model's #182 stands alone — and with bust risk at 18%, let the room catch up before paying a premium.
