Risk and opportunity flags

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

Isaiah Johnson
Risks
  • Older prospect
    Age 23.4 at draft. Slightly older than the cohort median (~22.5); upside ceiling is trimmed.
  • Comp group bust rate
    3 of 4 closest comps with NFL outcomes washed out: Prince Charles Iworah, Fabian Moreau, Brian Allen. The neighborhood in feature space is dangerous.
Opportunities
No standout upside flags.
Corey Ballentine
Risks
  • Older prospect
    Age 23.0 at draft. Slightly older than the cohort median (~22.5); upside ceiling is trimmed.
Opportunities
  • Consensus says higher
    1 board have him at mean rank #105; model has him #192 — a 87-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.

Isaiah Johnson

Draftanomics projects Isaiah Johnson (age 23.4 at draft) as a third-round / early Day 3 pick at #93 (range #44-#142, very wide band — too little on him yet to project tightly). Bust probability sits at 37% — 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: Prince Charles Iworah (Bust), Fabian Moreau (Bust), Brian Allen (Bust). Ceiling is Craig Mager (Starter); floor is Dexter McDonald (Contributor). 3 of 4 closest comps with NFL outcomes washed out: Prince Charles Iworah, Fabian Moreau, Brian Allen. The neighborhood in feature space is dangerous. The call is a value lean: #93 against a consensus #106 is a 13-spot edge — enough to move him up the queue, not enough to reach a round early, with older prospect the tax on that edge.

Corey Ballentine

Draftanomics projects Corey Ballentine (age 23.0 at draft) as a Day 3 dart throw at #192 (range #175-#209, wide band). Bust probability sits at 0% — low. Age 23.0 at draft. Slightly older than the cohort median (~22.5); upside ceiling is trimmed. The call is a genuine fade: the room's consensus prices him around #105 and the model won't take him before #192 — a 87-spot markdown. The discount is earned — older prospect leads the case against.
