Risk and opportunity flags

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

Marlon Mack
Risks
  • Comp group has bust risk
    2 of 5 closest comps with NFL outcomes ended up backups or busts: David Cobb, Josh Robinson. Mixed signal from history.
  • Negative per-play impact
    PPA avg_all 0.239 — per-snap contribution is below-average for the position. Volume stats overstate the impact.
Opportunities
  • Consensus says higher
    5 boards have him at mean rank #78; model has him #112 — a 34-spot fade. Analysts converging this much above the model is a tell that the model is undervaluing him.
  • Promising comp group
    3 of 5 closest comps with NFL outcomes hit Starter-or-better: Tevin Coleman, Jay Ajayi, Jeremy Langford.
Christian McCaffrey
Risks
  • Negative per-play impact
    PPA avg_all 0.263 — per-snap contribution is below-average for the position. Volume stats overstate the impact.
Opportunities
  • Strong comp group
    4 of 5 closest comps with NFL outcomes became Starters or Franchise players: Jeremy Langford, Tevin Coleman, Jay Ajayi (+1 more). The historical neighborhood overwhelmingly produced NFL contributors.

Verdict

The model's plain-English read.

Marlon Mack

Draftanomics projects Marlon Mack (age 21.1 at draft) as a mid-round flyer at #112 (range #83-#141, very wide band — too little on him yet to project tightly). Bust probability sits at 0% — low. The comp set is strong: 3 of 5 closest comps with known NFL outcomes became starters or better. Closest comps: David Cobb (Bust), Tevin Coleman (Franchise), Josh Robinson (Bust). Ceiling is Tevin Coleman (Franchise); floor is Jeremy Langford (Starter). School SP+ 9.8 (AMERICAN ATHLETIC). Strong program among non-Power-5 — the prospect dominated against decent competition. 2 of 5 closest comps with NFL outcomes ended up backups or busts: David Cobb, Josh Robinson. Mixed signal from history. The call is a genuine fade: the room's consensus prices him around #78 and the model won't take him before #112 — a 34-spot markdown. The discount is earned — comp group has bust risk leads the case against.

Christian McCaffrey

Draftanomics projects Christian McCaffrey (age 20.9 at draft) as a first-round pick at #17 (range #1-#44, wide band). Bust probability sits at 0% — low. The comp set is strong: 4 of 5 closest comps with known NFL outcomes became starters or better. Closest comps: David Cobb (Bust), Jeremy Langford (Starter), Tevin Coleman (Franchise). Ceiling is T.J. Yeldon (Franchise); floor is Jeremy Langford (Starter). PPA avg_all 0.263 — per-snap contribution is below-average for the position. Volume stats overstate the impact. The call is a hold at slot: the model's #17 sits within 3 spots of the room's #20 — no market edge to chase, so take him where he sits, and let the 0% bust probability break ties on draft day.
