NFL Scheme Fit
NFL Scheme Fit
- Outside-zone / wide-zone OL system
San Francisco 49ers · Los Angeles Rams · Detroit Lions · Miami Dolphins
Scheme matches are bucketed from the prospect's height, weight, and (for WRs) archetype tag against a static lookup of which NFL teams currently run each scheme family.
Rookie Contract & Landing-Spot Outlook
Projected Rookie Contract Value
~$4.3M – $4.6M (4-year deal) · Pick range: #161-200 · ~10% guaranteed
Minimum 4-yr deal + small bonus
Best-Case / Worst-Case Landing Spot
Why: OT listed in their top-5 positional needs; runs a scheme that maximizes his profile.
Year-1 arc: Day-1 starter window with cap-controlled rookie-contract production.
Why: runs a scheme that doesn't naturally amplify his profile.
Year-1 arc: Depth-chart competition + special-teams reps as Year-1 baseline.
Contract band uses the 2026 NFL CBA rookie wage scale projected from the prospect's expected pick range; guarantee % is the slot-default at that pick. Landing-spot best/worst case is derived from TEAMS data (positional needs + scheme overlap minus same-position R1 conflicts) — not a claim that either team has expressed interest.
Versatility, Limits & Roster Pathway
Day-3 NFL Roster Pathway
Day 3 OL projection means inactive-on-gameday is the default — versatility across multiple OL spots (swing-T, G/C flex) is the typical roster differentiator.
Derived from height/weight against the 2026 position cohort and the prospect's projected round. Versatility callouts identify alternate alignments NFL teams have historically used for similar size profiles. Limiting-trait notes flag the single most-cited measurable concern; severity reflects how often that flag ends a Day 1 starter projection. Roster-pathway notes describe the realistic Year 1 NFL role for Day 3 picks.
