Risk and opportunity flags

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

Iman Marshall
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 #199; model has him #106 — a 93-spot gap. When boards fade a player this hard, the model is usually the one missing something.
  • Comp group bust rate
    2 of 3 closest comps with NFL outcomes washed out: Doran Grant, Damian Swann. The neighborhood in feature space is dangerous.
Opportunities
No standout upside flags.
Kendall Sheffield
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.
  • Comp group bust rate
    4 of 5 closest comps with NFL outcomes washed out: Cyrus Jones, Jourdan Lewis, Damian Swann (+1 more). The neighborhood in feature space is dangerous.
Opportunities
  • Consensus says higher
    2 boards have him at mean rank #92; model has him #248 — a 156-spot fade. Analysts converging this much above the model is a tell that the model is undervaluing him.

Verdict

The model's plain-English read.

Iman Marshall

Draftanomics projects Iman Marshall (age 22.1 at draft) as a mid-round flyer at #106 (range #87-#125, wide band). Bust probability sits at 28% — manageable. The comp set is dangerous: 2 of 3 closest comps with known NFL outcomes washed out as backups or busts. Closest comps: Quandre Diggs (Franchise), Blake Countess (Contributor), Doran Grant (Bust). Ceiling is Quandre Diggs (Franchise); floor is Blake Countess (Contributor). 2 of 3 closest comps with NFL outcomes washed out: Doran Grant, Damian Swann. The neighborhood in feature space is dangerous. The call is a conviction buy: the model has him 93 spots ahead of the room (board #106 vs consensus #199), and at a 28% bust probability the edge is worth paying for.

Kendall Sheffield

Draftanomics projects Kendall Sheffield (age 22.9 at draft) as a Day 3 dart throw at #248 (range #211-#285, very wide band — too little on him yet to project tightly). Bust probability sits at 29% — manageable. The comp set is dangerous: 4 of 5 closest comps with known NFL outcomes washed out as backups or busts. Closest comps: Cyrus Jones (Bust), Jourdan Lewis (Bust), Kevon Seymour (Starter). Ceiling is Kevon Seymour (Starter); floor is Damian Swann (Bust). 4 of 5 closest comps with NFL outcomes washed out: Cyrus Jones, Jourdan Lewis, Damian Swann (+1 more). The neighborhood in feature space is dangerous. The call is a genuine fade: the room's consensus prices him around #92 and the model won't take him before #248 — a 156-spot markdown. The discount is earned — comp group bust rate leads the case against.
