Risk and opportunity flags

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

Brian Robinson Jr.
Risks
  • Older prospect
    Age 23.1 at draft. Slightly older than the cohort median (~22.5); upside ceiling is trimmed.
  • Comp group bust rate
    2 of 2 closest comps with NFL outcomes washed out: Ke'Shawn Vaughn, La'Mical Perine. The neighborhood in feature space is dangerous.
  • Negative per-play impact
    PPA avg_all 0.185 — per-snap contribution is below-average for the position. Volume stats overstate the impact.
Opportunities
  • Breakout production arc
    Career trajectory in rushing yards: 441 → 483 → 1343. Production rose every season — the kind of upward arc that often continues into the league.
James Cook
Risks
  • Comp group bust rate
    2 of 2 closest comps with NFL outcomes washed out: Dexter Williams, Bo Scarbrough. The neighborhood in feature space is dangerous.
  • Negative per-play impact
    PPA avg_all 0.334 — per-snap contribution is below-average for the position. Volume stats overstate the impact.
Opportunities
  • Consensus says higher
    25 boards have him at mean rank #97; model has him #157 — a 60-spot fade. Analysts converging this much above the model is a tell that the model is undervaluing him.
  • Breakout production arc
    Career trajectory in rushing yards: 188 → 303 → 728. Production rose every season — the kind of upward arc that often continues into the league.
Isaiah Spiller
Risks
  • Average-to-below athletic profile
    RAS 4.28 (42th percentile at RB). Athleticism is average at best for the position.
  • Comp group bust rate
    3 of 5 closest comps with NFL outcomes washed out: Derrius Guice, D'Onta Foreman, Wayne Gallman. The neighborhood in feature space is dangerous.
  • Negative per-play impact
    PPA avg_all 0.158 — per-snap contribution is below-average for the position. Volume stats overstate the impact.
Opportunities
No standout upside flags.

Verdict

The model's plain-English read.

Brian Robinson Jr.

Draftanomics projects Brian Robinson Jr. (age 23.1 at draft) as a third-round / early Day 3 pick at #91 (range #52-#130, very wide band — too little on him yet to project tightly). Bust probability sits at 0% — low. The comp set is dangerous: 2 of 2 closest comps with known NFL outcomes washed out as backups or busts. Closest comps: Ke'Shawn Vaughn (Bust), La'Mical Perine (Bust), Eno Benjamin (Contributor). Ceiling is Joshua Kelley (Contributor); floor is Eno Benjamin (Contributor). Career trajectory in rushing yards: 441 → 483 → 1343. Production rose every season — the kind of upward arc that often continues into the league. 2 of 2 closest comps with NFL outcomes washed out: Ke'Shawn Vaughn, La'Mical Perine. The neighborhood in feature space is dangerous. The call is a hold at slot: the model's #91 sits within 10 spots of the room's #81 — no market edge to chase, so take him where he sits, and let the 0% bust probability break ties on draft day.

James Cook

Draftanomics projects James Cook (age 22.6 at draft) as a mid-round flyer at #157 (range #111-#203, very wide band — too little on him yet to project tightly). Bust probability sits at 0% — low. The comp set is dangerous: 2 of 2 closest comps with known NFL outcomes washed out as backups or busts. Closest comps: Mike Weber, Damien Harris (Contributor), Dexter Williams (Bust). Ceiling is Royce Freeman (Contributor); floor is Mike Weber. Career trajectory in rushing yards: 188 → 303 → 728. Production rose every season — the kind of upward arc that often continues into the league. 2 of 2 closest comps with NFL outcomes washed out: Dexter Williams, Bo Scarbrough. The neighborhood in feature space is dangerous. The call is a genuine fade: the room's consensus prices him around #97 and the model won't take him before #157 — a 60-spot markdown. The discount is earned — comp group bust rate leads the case against.

Isaiah Spiller

Draftanomics projects Isaiah Spiller (age 20.7 at draft) as a third-round / early Day 3 pick at #73 (range #50-#96, wide band). Bust probability sits at 0% — low. The comp set is dangerous: 3 of 5 closest comps with known NFL outcomes washed out as backups or busts. Closest comps: David Montgomery (Starter), D'Andre Swift (Starter), Derrius Guice (Bust). Ceiling is D'Andre Swift (Starter); floor is David Montgomery (Starter). 3 of 5 closest comps with NFL outcomes washed out: Derrius Guice, D'Onta Foreman, Wayne Gallman. The neighborhood in feature space is dangerous. The call is a hold at slot: the model's #73 sits within 6 spots of the room's #67 — no market edge to chase, so take him where he sits, and let the 0% bust probability break ties on draft day.
