Risk and opportunity flags

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

Roy Lopez
Risks
  • Older prospect
    Age 23.7 at draft. Slightly older than the cohort median (~22.5); upside ceiling is trimmed.
  • Average-to-below athletic profile
    RAS 3.54 (35th percentile at DL). Athleticism is average at best for the position.
  • Consensus skeptic
    1 board place him at mean rank #347; model has him #223 — a 124-spot gap. When boards fade a player this hard, the model is usually the one missing something.
Opportunities
No standout upside flags.
Jonathan Marshall
Risks
  • Older prospect
    Age 23.6 at draft. Slightly older than the cohort median (~22.5); upside ceiling is trimmed.
  • Consensus skeptic
    1 board place him at mean rank #243; model has him #167 — a 76-spot gap. When boards fade a player this hard, the model is usually the one missing something.
  • Comp group has bust risk
    2 of 4 closest comps with NFL outcomes ended up backups or busts: Renell Wren, Dakota Allen. Mixed signal from history.
Opportunities
No standout upside flags.
Khyiris Tonga
Risks
  • Older prospect
    Age 24.8 at draft. Players entering the league past 24 hit fewer career milestones — the developmental window is already compressed before they take an NFL snap.
  • Average-to-below athletic profile
    RAS 3.47 (34th percentile at DL). Athleticism is average at best for the position.
  • Below-cohort college production
    Position-cohort z-score on production composite is -1.17 — well below the front7 average. Raw box-score output didn't keep pace with peers.
Opportunities
  • Promising comp group
    2 of 3 closest comps with NFL outcomes hit Starter-or-better: L.J. Collier, E.J. Speed.

Verdict

The model's plain-English read.

Roy Lopez

Draftanomics projects Roy Lopez (age 23.7 at draft) as a Day 3 dart throw at #223 (range #194-#252, very wide band — too little on him yet to project tightly). 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: Jullian Taylor (Bust), Sebastian Joseph-Day (Starter), Dakota Allen (Bust). Ceiling is E.J. Speed (Starter); floor is Sebastian Joseph-Day (Starter). 3 of 5 closest comps with NFL outcomes washed out: Jullian Taylor, Dakota Allen, Renell Wren. The neighborhood in feature space is dangerous. The call is a conviction buy: the model has him 124 spots ahead of the room (board #223 vs consensus #347), and at a 0% bust probability the edge is worth paying for.

Jonathan Marshall

Draftanomics projects Jonathan Marshall (age 23.6 at draft) as a mid-round flyer at #167 (range #113-#221, very wide band — too little on him yet to project tightly). Bust probability sits at 0% — low. The comp set is mixed: 2 starters-or-better vs 2 backups-or-busts among the 4 comps with known outcomes. Closest comps: Renell Wren (Bust), Dakota Allen (Bust), Sebastian Joseph-Day (Starter). Ceiling is L.J. Collier (Starter); floor is P.J. Johnson. Age 23.6 at draft. Slightly older than the cohort median (~22.5); upside ceiling is trimmed. The call is a conviction buy: the model has him 76 spots ahead of the room (board #167 vs consensus #243), and at a 0% bust probability the edge is worth paying for.

Khyiris Tonga

Draftanomics projects Khyiris Tonga (age 24.8 at draft) as a Day 3 dart throw at #191 (range #142-#240, very wide band — too little on him yet to project tightly). Bust probability sits at 4% — low. The comp set is strong: 2 of 3 closest comps with known NFL outcomes became starters or better. Closest comps: Treyvon Hester (Bust), Marquis Haynes (Contributor), Nathan Shepherd (Contributor). Ceiling is L.J. Collier (Starter); floor is Marquis Haynes (Contributor). Age 24.8 at draft. Players entering the league past 24 hit fewer career milestones — the developmental window is already compressed before they take an NFL snap. The call is a lean fade: the model sits 22 spots below the room's consensus #169 — don't pay sticker price. The discount is earned — older prospect leads the case against.
