Risk and opportunity flags

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

Donnie Lewis Jr.
Risks
  • Missed entire rookie season
    Drafted #221 by CLE in 2019 but recorded ZERO regular-season NFL snaps. Year-1 absence is one of the strongest single-signal bust predictors we have.
  • 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
    3 of 4 closest comps with NFL outcomes washed out: Shaquill Griffin, Ahkello Witherspoon, Rasul Douglas. The neighborhood in feature space is dangerous.
Opportunities
No standout upside flags.

Verdict

The model's plain-English read.

Donnie Lewis Jr.

Draftanomics projects Donnie Lewis Jr. (age 22.8 at draft) as a Day 3 dart throw at #179 (range #149-#209, very wide band — too little on him yet to project tightly). Bust probability sits at 47% — elevated. The comp set is dangerous: 3 of 4 closest comps with known NFL outcomes washed out as backups or busts. Closest comps: Anthony Brown (Starter), Shaquill Griffin (Bust), Corn Elder. Ceiling is Anthony Brown (Starter); floor is Corn Elder. Drafted #221 by CLE in 2019 but recorded ZERO regular-season NFL snaps. Year-1 absence is one of the strongest single-signal bust predictors we have. The call is a hold: no public board ranks him, so the model's #179 stands alone — and with bust risk at 47%, let the room catch up before paying a premium.

Duke Shelley

Draftanomics projects Duke Shelley (age 22.5 at draft) as a Day 3 dart throw at #191 (range #159-#223, very wide band — too little on him yet to project tightly). Bust probability sits at 32% — real but not disqualifying. The comp set is dangerous: 3 of 4 closest comps with known NFL outcomes washed out as backups or busts. Closest comps: Jamal Agnew (Bust), Ryan Murphy (Bust), Tye Smith (Bust). Ceiling is Steven Nelson (Starter); floor is LeShaun Sims (Contributor). 3 of 4 closest comps with NFL outcomes washed out: Jamal Agnew, Ryan Murphy, Tye Smith. The neighborhood in feature space is dangerous. The call is a hold: no public board ranks him, so the model's #191 stands alone — and with bust risk at 32%, let the room catch up before paying a premium.
