Risk and opportunity flags

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

Tim Harris
Risks
  • Missed entire rookie season
    Drafted #198 by SFO in 2019 but recorded ZERO regular-season NFL snaps. Year-1 absence is one of the strongest single-signal bust predictors we have.
  • Older prospect
    Age 23.7 at draft. Slightly older than the cohort median (~22.5); upside ceiling is trimmed.
  • 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.
Opportunities
  • Consensus says higher
    1 board have him at mean rank #85; model has him #230 — a 145-spot fade. Analysts converging this much above the model is a tell that the model is undervaluing him.
Jaquan Johnson
Risks
  • Older prospect
    Age 23.4 at draft. Slightly older than the cohort median (~22.5); upside ceiling is trimmed.
  • 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 3 closest comps with NFL outcomes washed out: Joshua Holsey, Prince Charles Iworah, Cordrea Tankersley. The neighborhood in feature space is dangerous.
Opportunities
No standout upside flags.
Ka'dar Hollman
Risks
  • Older prospect
    Age 24.6 at draft. Players entering the league past 24 hit fewer career milestones — the developmental window is already compressed before they take an NFL snap.
  • 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: Taurean Nixon, Damontae Kazee, Joshua Holsey (+1 more). The neighborhood in feature space is dangerous.
Opportunities
No standout upside flags.

Verdict

The model's plain-English read.

Tim Harris

Draftanomics projects Tim Harris (age 23.7 at draft) as a Day 3 dart throw at #230 (range #212-#248, wide band). Bust probability sits at 66% — scary. The comp set is dangerous: 4 of 4 closest comps with known NFL outcomes washed out as backups or busts. Closest comps: Adrian Colbert (Bust), Joshua Holsey (Bust), Brian Allen (Bust). Ceiling is Dexter McDonald (Contributor); floor is Prince Charles Iworah (Bust). Drafted #198 by SFO 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 genuine fade: the room's consensus prices him around #85 and the model won't take him before #230 — a 145-spot markdown. The discount is earned — missed entire rookie season leads the case against.

Jaquan Johnson

Draftanomics projects Jaquan Johnson (age 23.4 at draft) as a third-round / early Day 3 pick at #71 (range #19-#123, very wide band — too little on him yet to project tightly). Bust probability sits at 13% — low. The comp set is dangerous: 3 of 3 closest comps with known NFL outcomes washed out as backups or busts. Closest comps: Dexter McDonald (Contributor), Joshua Holsey (Bust), Prince Charles Iworah (Bust). Ceiling is Will Redmond; floor is Dexter McDonald (Contributor). 3 of 3 closest comps with NFL outcomes washed out: Joshua Holsey, Prince Charles Iworah, Cordrea Tankersley. The neighborhood in feature space is dangerous. The call is a hold at slot: the model's #71 sits within 8 spots of the room's #79 — no market edge to chase, so take him where he sits, and let the 13% bust probability break ties on draft day.

Ka'dar Hollman

Draftanomics projects Ka'dar Hollman (age 24.6 at draft) as a Day 3 dart throw at #244 (range #216-#272, very wide band — too little on him yet to project tightly). Bust probability sits at 53% — elevated. The comp set is dangerous: 4 of 5 closest comps with known NFL outcomes washed out as backups or busts. Closest comps: Taurean Nixon (Bust), Darryl Roberts (Starter), Damontae Kazee (Bust). Ceiling is Darryl Roberts (Starter); floor is Taurean Nixon (Bust). Age 24.6 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 hold: no public board ranks him, so the model's #244 stands alone — and with bust risk at 53%, let the room catch up before paying a premium.
