Risk and opportunity flags

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

A.J. Derby
Risks
  • Missed entire rookie season
    Drafted #202 by NWE in 2015 but recorded ZERO regular-season NFL snaps. Year-1 absence is one of the strongest single-signal bust predictors we have.
  • Older prospect
    Age 23.6 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.
Opportunities
No standout upside flags.
Blake Bell
Risks
  • Older prospect
    Age 23.7 at draft. Slightly older than the cohort median (~22.5); upside ceiling is trimmed.
  • TE slow 40 (4.80s)
    40-yard dash of 4.80s — below-average separation speed for the position.
  • Below-cohort college production
    Position-cohort z-score on production composite is -3.05 — well below the skill average. Raw box-score output didn't keep pace with peers.
Opportunities
No standout upside flags.
Gerald Christian
Risks
  • Missed entire rookie season
    Drafted #256 by ARI in 2015 but recorded ZERO regular-season NFL snaps. Year-1 absence is one of the strongest single-signal bust predictors we have.
  • Older prospect
    Age 23.7 at draft. Slightly older than the cohort median (~22.5); upside ceiling is trimmed.
  • TE slow 40 (4.87s)
    40-yard dash of 4.87s — below-average separation speed for the position.
Opportunities
No standout upside flags.

Verdict

The model's plain-English read.

A.J. Derby

Draftanomics projects A.J. Derby (age 23.6 at draft) as a Day 2 pick at #52 (range #35-#69, wide band). Bust probability sits at 65% — scary. Drafted #202 by NWE in 2015 but recorded ZERO regular-season NFL snaps. Year-1 absence is one of the strongest single-signal bust predictors we have. The call is a hold: no public board ranks him, so the model's #52 stands alone — and with bust risk at 65%, let the room catch up before paying a premium.

Blake Bell

Draftanomics projects Blake Bell (age 23.7 at draft) as a Day 3 dart throw at #226 (range #224-#228, tight projection). Bust probability sits at 6% — low. Age 23.7 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 #226 stands alone — and with bust risk at 6%, let the room catch up before paying a premium.

Gerald Christian

Draftanomics projects Gerald Christian (age 23.7 at draft) as a Day 3 dart throw at #249 (range #247-#251, tight projection). Bust probability sits at 65% — scary. Drafted #256 by ARI in 2015 but recorded ZERO regular-season NFL snaps. Year-1 absence is one of the strongest single-signal bust predictors we have. The call is a hold: no public board ranks him, so the model's #249 stands alone — and with bust risk at 65%, let the room catch up before paying a premium.
