From conference scale to one position room.
The interface is designed for exploration first and evidence second: isolate a question, pin the answer, then export the view with its context intact.
Direct comparison
Put rivals on the same scale.
Move past roster averages. The head-to-head view reveals where one program is longer, heavier or more highly rated at the exact position groups that decide a matchup.
- Position-by-position splits
- Recruiting class or current roster
- Pin, annotate and export
Performance context
See what programs do with talent.
Recruiting is an input, not an outcome. The scoreboard brings composite talent, wins and SP+ together so development and underperformance are visible across seasons.
- Season-level roster composites
- Wins and advanced ratings
- Coach-era context
Transparent by design
A method you can inspect, not a black box.
Every chart names its player pool, unit of analysis and source. The app separates reported measurements from modeled comparisons and keeps the caveats beside the result.
Recruiting and rosters
247Sports classes and team rosters from 2016 through the current 2027 cycle, with portal additions included from 2021.
Comparable positions
Team labels, positions, measurements and ratings are standardized so like-for-like comparisons remain possible.
Results in context
Season records and SP+ from CollegeFootballData connect recruiting inputs to on-field football performance.
Limits stay visible
Program-reported heights and weights are directional, not lab measurements. Samples and definitions travel with each view.
