Risk and opportunity flags

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

JaCorey Shepherd
Risks
  • Missed entire rookie season
    Drafted #191 by PHI in 2015 but recorded ZERO regular-season NFL snaps. Year-1 absence is one of the strongest single-signal bust predictors we have.
  • CB slow 40 (4.62s)
    40-yard dash of 4.62s — historically corners above 4.55s rarely become NFL starters.
  • Not on any consensus board
    Model has him at pick #20 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.
Lorenzo Doss
Risks
  • Not on any consensus board
    Model has him at pick #67 but ZERO public big boards have him on their list. Either we're seeing something nobody else does, or the model is hallucinating.
  • Small-school competition
    School SP+ rating -15.0 (well below FBS median of 0). College production may not translate against NFL-quality DBs/pass-rushers. Schedule rank #65 (1=hardest).
Opportunities
No standout upside flags.
Quinten Rollins
Risks
  • CB slow 40 (4.57s)
    40-yard dash of 4.57s — historically corners above 4.55s rarely become NFL starters.
  • Small-school competition
    School SP+ rating -18.7 (well below FBS median of 0). College production may not translate against NFL-quality DBs/pass-rushers. Schedule rank #97 (1=hardest).
Opportunities

Verdict

The model's plain-English read.

JaCorey Shepherd

Draftanomics projects JaCorey Shepherd (age 22.1 at draft) as a first-round pick at #20 (range #10-#30, moderate band). Bust probability sits at 65% — scary. Drafted #191 by PHI 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 #20 stands alone — and with bust risk at 65%, let the room catch up before paying a premium.

Lorenzo Doss

Draftanomics projects Lorenzo Doss (age 21.0 at draft) as a third-round / early Day 3 pick at #67 (range #53-#81, wide band). Bust probability sits at 47% — elevated. School SP+ rating -15.0 (well below FBS median of 0). College production may not translate against NFL-quality DBs/pass-rushers. Schedule rank #65 (1=hardest). The call is a hold: no public board ranks him, so the model's #67 stands alone — and with bust risk at 47%, let the room catch up before paying a premium.

Quinten Rollins

Draftanomics projects Quinten Rollins (age 22.8 at draft) as a mid-round flyer at #162 (range #148-#176, wide band). Bust probability sits at 0% — low. 40-yard dash of 4.57s — historically corners above 4.55s rarely become NFL starters. The call is a hold: no public board ranks him, so the model's #162 stands alone — and with bust risk at 0%, let the room catch up before paying a premium.
