Risk and opportunity flags

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

Jamar Johnson
Risks
  • Average-to-below athletic profile
    RAS 3.91 (39th percentile at CB). Athleticism is average at best for the position.
  • CB slow 40 (4.58s)
    40-yard dash of 4.58s — historically corners above 4.55s rarely become NFL starters.
  • Comp group bust rate
    2 of 2 closest comps with NFL outcomes washed out: Cameron Sutton, Jordan Miller. The neighborhood in feature space is dangerous.
Opportunities
  • Consensus says higher
    24 boards have him at mean rank #86; model has him #143 — a 57-spot fade. Analysts converging this much above the model is a tell that the model is undervaluing him.
Jamien Sherwood
Risks
  • Average-to-below athletic profile
    RAS 4.02 (40th percentile at CB). Athleticism is average at best for the position.
  • CB slow 40 (4.76s)
    40-yard dash of 4.76s — historically corners above 4.55s rarely become NFL starters.
  • Consensus skeptic
    1 board place him at mean rank #187; model has him #141 — a 46-spot gap. When boards fade a player this hard, the model is usually the one missing something.
Opportunities
No standout upside flags.

Verdict

The model's plain-English read.

Jamar Johnson

Draftanomics projects Jamar Johnson (age 21.4 at draft) as a mid-round flyer at #143 (range #105-#181, very wide band — too little on him yet to project tightly). Bust probability sits at 28% — manageable. The comp set is dangerous: 2 of 2 closest comps with known NFL outcomes washed out as backups or busts. Closest comps: Greg Stroman (Contributor), Cameron Sutton (Bust), Jordan Miller (Bust). Ceiling is Isaac Yiadom (Contributor); floor is Greg Stroman (Contributor). 40-yard dash of 4.58s — historically corners above 4.55s rarely become NFL starters. The call is a genuine fade: the room's consensus prices him around #86 and the model won't take him before #143 — a 57-spot markdown. The discount is earned — average-to-below athletic profile leads the case against.

Jamien Sherwood

Draftanomics projects Jamien Sherwood (age 21.3 at draft) as a mid-round flyer at #141 (range #100-#182, very wide band — too little on him yet to project tightly). Bust probability sits at 27% — manageable. The comp set is dangerous: 2 of 3 closest comps with known NFL outcomes washed out as backups or busts. Closest comps: Rashad Fenton (Contributor), Greg Stroman (Contributor), Daryl Worley (Starter). Ceiling is Daryl Worley (Starter); floor is Greg Stroman (Contributor). 40-yard dash of 4.76s — historically corners above 4.55s rarely become NFL starters. The call is a conviction buy: the model has him 46 spots ahead of the room (board #141 vs consensus #187), and at a 27% bust probability the edge is worth paying for.
