Draft coverage runs on a private vocabulary used in public without translation. Most of it means something specific. Some of it means considerably less than it sounds like.
What a grade is actually measuring
The first thing to understand about a scouting grade is that it is a forecast, not an assessment. A scout is not scoring how good a player is now. He is scoring what the player is expected to become in the NFL, at a specific position, in a specific role.
That is why grades are strange to read from outside. A polished four-year starter who is already close to his ceiling can grade below a raw player with a year of production, because the question being answered is "what is this in three years?"
Clubs use their own numerical scales and they do not match each other. What travels between clubs — and what actually decides drafts — is the round value: this is a second-round player, this is a fourth-round player. Everything else is internal bookkeeping.
Two boards exist in every draft room:
- The horizontal board lists prospects by position, so you can see the whole class at cornerback at once.
- The vertical board is the stacked list of every player in the class, in order, regardless of position. This is the one they draft from.
Reconciling the two is where need enters. Pure "best player available" is close to a myth; what clubs actually do is take the highest player in a tier, and use need to break ties within the tier. When a club appears to reach, it is usually because its tier boundaries do not sit where the public's do.
The combine drills and what they test
| Drill | What it measures | What it is worth |
|---|---|---|
| 40-yard dash | Long speed | Matters most where players actually run 40 yards — receiver, corner, safety. For linemen the useful number buried inside it is the 10-yard split. |
| 10-yard split | Initial burst | The first step off the line. Far more relevant to interior linemen than the full 40. |
| Bench press (225 lb reps) | Strength endurance | Heavily confounded by arm length — long arms move the bar further. Weakly related to functional playing strength. |
| Vertical jump | Lower-body explosiveness | A decent proxy for power production. Correlates with the broad jump; the two together are more informative than either alone. |
| Broad jump | Horizontal explosiveness | Same underlying quality as the vertical, expressed forward. |
| 3-cone drill | Change of direction under a tight turn | The drill most often cited for edge rushers and receivers, because it approximates a real movement pattern. |
| 20-yard shuttle | Lateral quickness, short-area | Short-space acceleration and deceleration in both directions. |
The honest summary of the research: testing numbers in isolation have a weak relationship with NFL success. Study after study has looked for the correlation and found little of it across most positions. What testing does well is exclude — a player who cannot meet a positional athletic threshold is unlikely to survive, even if the tape looks good — and confirm, when tape and testing tell the same story.
Where a number carries genuine weight is when it disagrees with the tape. A player who looks slow and runs fast has usually got a technique or processing problem, which can be coached. A player who looks fast and runs slow was probably playing against poor competition.
Athleticism scores
RAS — Relative Athletic Score — is a 0-to-10 composite created by Kent Lee Platte that expresses a prospect's size and testing results relative to a historical database of players at the same position. Its value is that it does the normalising for you: a 4.6-second 40 is unremarkable for a receiver and extraordinary for an offensive tackle, and a single number handles that comparison.
It is a description of an athlete, not a prediction about a football player, and it is at its most useful as the athletic half of a two-part read alongside the tape.
The glossary
Bend. A pass rusher's ability to lean through the corner without losing speed — to turn the arc tight rather than running past the quarterback. Largely a hip and ankle flexibility trait, and one of the few things scouts genuinely believe cannot be taught.
Length. Arm length and wingspan, measured officially at the combine. A hard threshold at offensive tackle and cornerback, where the ability to make first contact before your opponent does is close to positional table stakes.
Play strength. Functional strength in pads at football speed, as distinct from weight-room strength. The distinction is the entire reason the bench press is treated with suspicion.
Twitch / explosiveness. Short-area quickness — how fast a player goes from still to moving. Distinct from long speed, and generally the more valuable of the two at the line of scrimmage.
High floor / high ceiling. Floor is the worst plausible outcome, ceiling the best. A polished, limited player is a high floor. A raw, exceptional athlete is a high ceiling. Clubs picking late in round one with a complete roster buy ceilings; clubs who must start the player in September buy floors.
Athletic upside. The polite version of: he tests better than he plays. Sometimes that is a coaching opportunity. Often it is the reason he was available.
Tweener. A player between positions — too small for one, too slow for another. Whether this is a fatal problem or an advantage depends almost entirely on whether a scheme exists that wants exactly that shape.
Scheme-diverse. He fits everywhere, so his value does not depend on who drafts him. Its opposite, a scheme-specific player, can be a first-round talent to two clubs and a fourth-round talent to the other thirty.
Medical grade. A separate grade from the football one, assigned by club doctors, usually on a pass/caution/fail-style scale. It is the most common invisible reason a player slides, and it is never explained publicly.
Character grade. Also separate, also unpublished, and the vaguest of all — it bundles genuine off-field concerns with everything from work habits to interview performance. It is where the least defensible parts of the process live.
Comp. A player comparison. Occasionally illuminating, more often a shortcut that transfers expectations a prospect has not earned. A comparison is useful when it names a specific trait and useless when it names a career.
Pro-ready. He can play in September. Says nothing at all about whether he will still be starting in year four.
