How We Rate
Every rating on Prime vs Now is informed by verifiable career statistics from Pro Football Reference, Basketball Reference, Sherdog, BoxRec, and official league records. Our editorial team translates those stats into attribute ratings — transparent, debatable, and always backed by a receipt.
Our Principles
Stats-Informed
Every attribute rating is derived from real statistics — career numbers, awards, efficiency metrics. The editorial team translates stats into 0–100 ratings you can interrogate.
Position-Fair
A wide receiver isn't penalized for not playing defense. Attributes are universal — every position is rated on the same 7 traits.
Era-Aware
Matchup rulesets adjust attribute weights by era. 70s rules favor toughness. Modern rules favor athleticism. Neutral rules treat all eras equally.
NFL Player Attributes (7)
What we measure and exactly how — detailed breakdown
Peak Dominance
PrimaryHow dominant was this player at their absolute best? This measures the height of their peak, not how long it lasted.
Measured By
- —MVP, DPOY, and major award wins
- —First-Team All-Pro selections
- —Peak single-season stats vs league average
- —Single-season records held
- —Dominance margin over contemporaries
Example: Jerry Rice's 22-TD, 1,848-yard 1987 season (12 games) scores 99. A solid starter with zero All-Pro nods scores 55–65.
Playmaking Ability
PrimaryCan this player change a game with a single play? Explosive, game-breaking talent that creates something out of nothing.
Measured By
- —Career touchdowns (all types)
- —Yards per attempt / yards per carry
- —Big play rate (20+ yard gains)
- —Return touchdowns and non-offensive scores
- —Game-changing turnover creation (INTs, forced fumbles)
Example: Randy Moss's 156 career TDs at 15.6 yards per reception scores 99. A possession receiver with 40 career TDs scores 65–75.
Clutch Factor
MajorDoes this player elevate when the stakes are highest? Postseason performance, championship moments, and pressure situations.
Measured By
- —Playoff win-loss record
- —Super Bowl appearances and wins
- —Postseason statistical performance vs regular season
- —4th-quarter comebacks and game-winning drives
- —Conference championship appearances
Example: Tom Brady's 7 Super Bowl wins and 42 4th-quarter comebacks scores 99. A great regular-season player who went 1-3 in the playoffs scores 65–75.
Football IQ
SupportingStatistical efficiency and situational execution — the measurable proxies for football intelligence.
Measured By
- —Turnover rate (INT%, fumble rate per touch)
- —Passer rating and QBR (QBs)
- —Penalty rate and pre-snap infraction frequency
- —3rd-down and red-zone conversion efficiency
- —Efficiency metrics relative to era (YPC, completion %, etc.)
Example: Aaron Rodgers' career 2.0% INT rate and 104.5 passer rating scores 95. A QB with 3.5%+ INT rate and sub-80 passer rating scores 65–75.
Toughness
SupportingPhysical play style and ability to perform through adversity. Measured by on-field physicality, not intangibles.
Measured By
- —Games played through documented injuries
- —Consecutive starts streaks
- —Physical play style metrics (tackles broken, yards after contact)
- —Performance in adverse conditions (weather, short rest)
- —Contact initiation rate (for offensive skill players)
Example: Brett Favre's 297 consecutive starts scores 99. A player who missed 3+ seasons to injuries and avoided contact scores 50–65.
Athleticism
SupportingRaw physical tools relative to position. Measurable athletic ability that can't be coached.
Measured By
- —NFL Combine metrics (40-yard dash, vertical jump, broad jump)
- —Height, weight, and speed combination relative to position
- —Shuttle and 3-cone times (agility)
- —Position-relative athletic scores (RAS, SPARQ)
- —Observable physical tools when combine data unavailable (pre-Combine era players)
Example: Calvin Johnson's 4.35s 40 at 6'5" 236 lbs scores 96. A receiver who ran 4.55+ and measured below average athletically scores 65–75.
All Attribute Systems
Every sport uses its own attribute set and weights
NFL Players (6 attributes)
Position-universal traits. Every attribute is traceable to a Pro Football Reference stat. No career-duration metrics — this is about who wins head-to-head.
NBA Players (8 attributes)
Covers both ends of the floor plus versatility and efficiency. Sources: Basketball Reference.
NBA Teams (8 attributes)
Team-level performance metrics for historic NBA squads.
NFL Teams (8 attributes)
Team-level performance metrics for historic NFL squads.
MMA Fighters (8 attributes)
Covers all phases of mixed martial arts. Sources: Sherdog, UFC Stats.
Boxing Fighters (8 attributes)
The sweet science broken into measurable components. Sources: BoxRec, CompuBox.
Rating Tiers
The overall rating is the weighted average of all 7 attributes. That number maps to a tier:
How Matchups Work
Attributes are compared head-to-head
Each of the 6 attributes is compared between both players. The difference is calculated for each.
Importance tiers shape the outcome
Primary attributes carry more influence than Supporting ones. Era rulesets can shift these priorities — 70s rules favor toughness, modern rules favor athleticism.
A probability is computed
The weighted differences are transformed into a win probability between 0% and 100%. The math is proprietary but the inputs are transparent.
Results are deterministic
Same inputs always produce the exact same output. A seeded tiebreaker prevents artificial 50/50 splits, but the same matchup always returns the same result. No AI judgment, no human override.
Scouting Report Ratings
In addition to the 7 engine attributes, every NFL player has a position-specific scouting report with 8 Madden-style ratings. These are display only — they show detailed breakdowns but do not affect matchup outcomes.
