Risk and opportunity flags

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

John Penisini
Risks
  • Athletic profile below NFL threshold
    RAS 2.37 (23th percentile vs DT prospects in a 312-yr Combine population). Below the 30th-percentile bar that most NFL starters clear.
  • Consensus skeptic
    1 board place him at mean rank #215; model has him #183 — a 32-spot gap. When boards fade a player this hard, the model is usually the one missing something.
  • Comp group bust rate
    3 of 5 closest comps with NFL outcomes washed out: Ryan Glasgow, Vincent Valentine, Nazair Jones. The neighborhood in feature space is dangerous.
Opportunities
No standout upside flags.
Bravvion Roy
Risks
  • Older prospect
    Age 23.5 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.
  • Comp group has bust risk
    2 of 5 closest comps with NFL outcomes ended up backups or busts: Vincent Taylor, Grover Stewart. Mixed signal from history.
Opportunities
  • Promising comp group
    3 of 5 closest comps with NFL outcomes hit Starter-or-better: Anthony Zettel, Darius Kilgo, David Parry.
Jashon Cornell
Risks
No major risks flagged.

Verdict

The model's plain-English read.

John Penisini

Draftanomics projects John Penisini (age 22.9 at draft) as a Day 3 dart throw at #183 (range #167-#199, wide band). Bust probability sits at 10% — low. The comp set is dangerous: 3 of 5 closest comps with known NFL outcomes washed out as backups or busts. Closest comps: Ryan Glasgow (Bust), Vincent Valentine (Bust), David Parry (Franchise). Ceiling is David Parry (Franchise); floor is Carl Davis (Starter). RAS 2.37 (23th percentile vs DT prospects in a 312-yr Combine population). Below the 30th-percentile bar that most NFL starters clear. The call is a conviction buy: the model has him 32 spots ahead of the room (board #183 vs consensus #215), and at a 10% bust probability the edge is worth paying for.

Bravvion Roy

Draftanomics projects Bravvion Roy (age 23.5 at draft) as a Day 3 dart throw at #203 (range #186-#220, wide band). Bust probability sits at 4% — low. The comp set is strong: 3 of 5 closest comps with known NFL outcomes became starters or better. Closest comps: Anthony Zettel (Starter), Darius Kilgo (Starter), Vincent Taylor (Bust). Ceiling is David Parry (Franchise); floor is Darius Kilgo (Starter). Age 23.5 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 #203 stands alone — and with bust risk at 4%, let the room catch up before paying a premium.
