Risk and opportunity flags

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

Isaac Yiadom
Risks
No major risks flagged.
Opportunities
  • Consensus says higher
    5 boards have him at mean rank #86; model has him #120 — a 34-spot fade. Analysts converging this much above the model is a tell that the model is undervaluing him.
  • Promising comp group
    2 of 3 closest comps with NFL outcomes hit Starter-or-better: Artie Burns, Kendall Fuller.
Cornell Armstrong
Risks
  • 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.
  • Consensus skeptic
    1 board place him at mean rank #993; model has him #239 — a 754-spot gap. When boards fade a player this hard, the model is usually the one missing something.
  • Comp group bust rate
    3 of 4 closest comps with NFL outcomes washed out: Tye Smith, Tray Walker, D'Joun Smith. The neighborhood in feature space is dangerous.
Opportunities
No standout upside flags.
Greg Stroman
Risks
  • Consensus skeptic
    1 board place him at mean rank #374; model has him #199 — a 175-spot gap. When boards fade a player this hard, the model is usually the one missing something.
Opportunities
  • Strong comp group
    4 of 4 closest comps with NFL outcomes became Starters or Franchise players: Daryl Worley, Rashard Robinson, Steven Nelson (+1 more). The historical neighborhood overwhelmingly produced NFL contributors.

Verdict

The model's plain-English read.

Isaac Yiadom

Draftanomics projects Isaac Yiadom (age 22.2 at draft) as a mid-round flyer at #120 (range #65-#175, very wide band — too little on him yet to project tightly). Bust probability sits at 0% — low. The comp set is strong: 2 of 3 closest comps with known NFL outcomes became starters or better. Closest comps: Artie Burns (Starter), Harlan Miller (Contributor), Kendall Fuller (Starter). Ceiling is Artie Burns (Starter); floor is Kalan Reed (Backup). The call is a genuine fade: the room's consensus prices him around #86 and the model won't take him before #120 — a 34-spot markdown. The 34-spot markdown rests on thin verified signal rather than a named flaw — the model hasn't seen enough yet to match the room's conviction.

Cornell Armstrong

Draftanomics projects Cornell Armstrong (age 22.6 at draft) as a Day 3 dart throw at #239 (range #214-#264, wide band). Bust probability sits at 0% — low. The comp set is dangerous: 3 of 4 closest comps with known NFL outcomes washed out as backups or busts. Closest comps: Tye Smith (Bust), LeShaun Sims (Contributor), Tray Walker (Bust). Ceiling is Steven Nelson (Starter); floor is LeShaun Sims (Contributor). 3 of 4 closest comps with NFL outcomes washed out: Tye Smith, Tray Walker, D'Joun Smith. The neighborhood in feature space is dangerous. The call is a conviction buy: the model has him 754 spots ahead of the room (board #239 vs consensus #993), and at a 0% bust probability the edge is worth paying for.

Greg Stroman

Draftanomics projects Greg Stroman (age 22.1 at draft) as a Day 3 dart throw at #199 (range #167-#231, very wide band — too little on him yet to project tightly). Bust probability sits at 0% — low. The comp set is strong: 4 of 4 closest comps with known NFL outcomes became starters or better. Closest comps: Daryl Worley (Starter), Rashard Robinson (Starter), LeShaun Sims (Contributor). Ceiling is Marcus Peters (Franchise); floor is LeShaun Sims (Contributor). The call is a conviction buy: the model has him 175 spots ahead of the room (board #199 vs consensus #374), and at a 0% bust probability the edge is worth paying for.
