Risk and opportunity flags

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

Jameis Winston
Risks
  • Not on any consensus board
    Model has him at pick #46 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.
Garrett Grayson
Risks
  • Missed entire rookie season
    Drafted #75 by NOR 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 23.9 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
  • Breakout production arc
    Career trajectory in passing yards: 542 → 946 → 3696 → 4006. Production rose every season — the kind of upward arc that often continues into the league.
Marcus Mariota
Risks
  • Not on any consensus board
    Model has him at pick #94 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.

Verdict

The model's plain-English read.

Jameis Winston

Draftanomics projects Jameis Winston (age 21.3 at draft) as a Day 2 pick at #46 (range #44-#48, tight projection). Bust probability sits at 15% — manageable. The call is a hold: no public board ranks him, so the model's #46 stands alone — and with bust risk at 15%, let the room catch up before paying a premium.

Garrett Grayson

Draftanomics projects Garrett Grayson (age 23.9 at draft) as a Day 3 dart throw at #221 (range #219-#223, tight projection). Bust probability sits at 65% — scary. Career trajectory in passing yards: 542 → 946 → 3696 → 4006. Production rose every season — the kind of upward arc that often continues into the league. Drafted #75 by NOR 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 #221 stands alone — and with bust risk at 65%, let the room catch up before paying a premium.

Marcus Mariota

Draftanomics projects Marcus Mariota (age 21.5 at draft) as a third-round / early Day 3 pick at #94 (range #92-#96, tight projection). Bust probability sits at 7% — low. The call is a hold: no public board ranks him, so the model's #94 stands alone — and with bust risk at 7%, let the room catch up before paying a premium.
