Risk and opportunity flags

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

Taurean Nixon
Risks
  • Missed entire rookie season
    Drafted #251 by DEN 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 24.2 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.
Darryl Roberts
Risks
  • Missed entire rookie season
    Drafted #247 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 24.4 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
  • Mid-major standout
    School SP+ 16.8 (SUN BELT). Strong program among non-Power-5 — the prospect dominated against decent competition.
Dexter McDonald
Risks
  • Older prospect
    Age 23.4 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.
  • Small-school competition
    School SP+ rating -9.8 (well below FBS median of 0). College production may not translate against NFL-quality DBs/pass-rushers. Schedule rank #19 (1=hardest).
Opportunities
No standout upside flags.

Verdict

The model's plain-English read.

Taurean Nixon

Draftanomics projects Taurean Nixon (age 24.2 at draft) as a Day 3 dart throw at #215 (range #201-#229, wide band). Bust probability sits at 65% — scary. Drafted #251 by DEN 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 #215 stands alone — and with bust risk at 65%, let the room catch up before paying a premium.

Darryl Roberts

Draftanomics projects Darryl Roberts (age 24.4 at draft) as a Day 3 dart throw at #252 (range #238-#266, wide band). Bust probability sits at 65% — scary. School SP+ 16.8 (SUN BELT). Strong program among non-Power-5 — the prospect dominated against decent competition. Drafted #247 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 #252 stands alone — and with bust risk at 65%, let the room catch up before paying a premium.

Dexter McDonald

Draftanomics projects Dexter McDonald (age 23.4 at draft) as a Day 3 dart throw at #186 (range #172-#200, wide band). Bust probability sits at 47% — elevated. Age 23.4 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 #186 stands alone — and with bust risk at 47%, let the room catch up before paying a premium.
