Risk and opportunity flags

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

Joshua Dobbs
Risks
  • Missed entire rookie season
    Drafted #135 by PIT in 2017 but recorded ZERO regular-season NFL snaps. Year-1 absence is one of the strongest single-signal bust predictors we have.
Opportunities
  • Consensus says higher
    2 boards have him at mean rank #82; model has him #165 — a 84-spot fade. Analysts converging this much above the model is a tell that the model is undervaluing him.
  • Strong comp group
    5 of 5 closest comps with NFL outcomes became Starters or Franchise players: Brett Hundley, Marcus Mariota, Trevor Siemian (+2 more). The historical neighborhood overwhelmingly produced NFL contributors.
Chad Kelly
Risks
  • Missed entire rookie season
    Drafted #253 by DEN in 2017 but recorded ZERO regular-season NFL snaps. Year-1 absence is one of the strongest single-signal bust predictors we have.
  • Older prospect
    Age 23.1 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
  • Strong comp group
    4 of 4 closest comps with NFL outcomes became Starters or Franchise players: Brett Hundley, Bryce Petty, Sean Mannion (+1 more). The historical neighborhood overwhelmingly produced NFL contributors.

Verdict

The model's plain-English read.

Joshua Dobbs

Draftanomics projects Joshua Dobbs (age 22.2 at draft) as a mid-round flyer at #165 (range #111-#219, very wide band — too little on him yet to project tightly). Bust probability sits at 65% — scary. The comp set is strong: 5 of 5 closest comps with known NFL outcomes became starters or better. Closest comps: Brett Hundley (Starter), Marcus Mariota (Franchise), Trevor Siemian (Franchise). Ceiling is Marcus Mariota (Franchise); floor is Brett Hundley (Starter). Career trajectory in passing yards: 695 → 1206 → 2291 → 2946. Production rose every season — the kind of upward arc that often continues into the league. Drafted #135 by PIT in 2017 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 genuine fade: the room's consensus prices him around #82 and the model won't take him before #165 — a 84-spot markdown. The discount is earned — missed entire rookie season leads the case against.

Chad Kelly

Draftanomics projects Chad Kelly (age 23.1 at draft) as a Day 3 dart throw at #250 (range #219-#281, very wide band — too little on him yet to project tightly). Bust probability sits at 65% — scary. The comp set is strong: 4 of 4 closest comps with known NFL outcomes became starters or better. Closest comps: Brett Hundley (Starter), Garrett Grayson, Bryce Petty (Starter). Ceiling is Jameis Winston (Franchise); floor is Garrett Grayson. Drafted #253 by DEN in 2017 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 conviction buy: the model has him 79 spots ahead of the room (board #250 vs consensus #329) — but size the bet for the 65% bust probability; this is a price edge, not a safety edge.
