The NFL Scouting Combine: Tests, Measurements and What Matters

By 4Football Staff · October 7, 2026 · 10 min read

Hundreds of draft prospects are measured, tested, examined and interviewed in a few days. Here is what happens at the Combine, what each drill tells teams and how much it really matters.

Late each winter, a large group of the best college football players gathers in one city for several days, and almost none of what they do looks like football. They stand on scales. They have their arms measured. They run forty yards in a straight line on an artificial surface while a stopwatch system records the result to the hundredth of a second. They lift a bar, jump as high as they can, answer questions from team executives and spend hours in medical exams.

This is the NFL Scouting Combine, and it is one of the strangest events in sports. Its centerpiece is a series of tests that are, at best, an indirect measure of what a player does on Sundays. Yet it draws intense attention from teams and fans alike, and a single good or bad result can change a player's reputation for months.

This guide explains what the Combine is, how prospects get invited, what happens day by day, what each test measures and, most importantly, how much weight teams actually place on the results. Details such as the dates and the list of invited players change annually, so we focus on the structure that stays the same.

What the Combine is

The Combine is an annual event, run by the league and its scouting organization, in which draft-eligible college players are evaluated by representatives of all 32 teams in one place at one time. It takes place in the late winter, after the college season and before the draft, and it has been held in Indianapolis for decades, using a convention center and a nearby stadium.

The purpose is efficiency. Before the Combine existed in its modern form, teams sent scouts to individual campuses and collected information separately. The Combine lets every team see the same players doing the same tests under the same conditions. It also centralizes the medical exams, which means a player does not have to travel to dozens of team facilities for examinations. In this sense the Combine is a shared data-gathering exercise.

The word "Combine" itself reflects the history: scouting groups once combined their resources to evaluate prospects, and the name stayed after the arrangement became an official league event.

Who gets invited

Only a few hundred players are invited, which is a small share of the players who are draft eligible. An invitation comes from a league committee that reviews player information provided by scouts. It is not a guarantee of being drafted, and not being invited does not rule it out. Plenty of drafted players were never at the Combine, including those from smaller schools who are evaluated at other events.

Some points to keep in mind:

• Eligibility. To be invited, a player must be eligible for the draft, which is a topic we cover in how NFL draft eligibility works for college players.
• Roster size. The invited group is large enough to cover every position, with several players at each. The number of invitees at each position reflects how many players that position needs.
• Early entrants. Players who leave college with eligibility remaining must declare for the draft, a decision discussed in our article on declaring early.
• Other showcases. College all-star games, such as the Senior Bowl, and individual campus events fill in for players who are not invited.

How the schedule works

Players do not arrive all at once. They come in position groups, and each group spends a few days in the city. The schedule is organized so that all the groups go through the same process in sequence. A typical stay includes:

1. Arrival and check-in. Players receive their schedule and credentials.
2. Measurements and medical exams. This is a long day of weighing, measuring and examinations.
3. Interviews and meetings. Players meet with team representatives and take written assessments.
4. On-field workouts. The televised portion, when players run the drills in front of scouts, coaches and executives.
5. Departure. Players go home or to the next phase of preparation.

The on-field workouts are what most fans see, but they are not the most important part from the teams' point of view. For many clubs, the medical and interview portions carry greater weight.

The measurements

Before any drill, each player is measured. The standard numbers include height, weight, arm length, hand size and, for many players, wingspan. These measurements are not arbitrary. Different positions have different physical demands, and certain dimensions help or hinder a player in specific ways.

• Arm length matters for linemen and defensive backs, because longer arms provide leverage and reach.
• Hand size matters for quarterbacks, who must grip the ball, and for some other positions where ball security is a concern.
• Height and weight shape the scouting profile at every position. A team that runs a certain scheme may prefer particular builds.

Teams have their own preferences and thresholds, and those are rarely made public. It is common for fans to hear that a certain position "needs" a certain measurement, but such claims are generalizations. Players have succeeded despite not meeting a rule of thumb, and others have failed despite meeting it.

The athletic tests

The core of the on-field portion is a group of standardized tests. Each isolates a physical quality.

Several things are worth saying about these tests.

The 40-yard dash

This is the most famous test, and the one that gets the most attention. It is a measure of straight-line speed over a short distance. For a receiver or cornerback, a fast time suggests the ability to run past defenders. For an offensive lineman, a good time shows athleticism for a large person. The ten-yard split is often more informative for linemen, because it measures how quickly a player gets going. Our guide to training for the 40-yard dash explains how players prepare for it.

The test has limits. Football players rarely run forty yards in a straight line from a stationary start, and a fast time does not guarantee a player can play fast in pads, against defenders and in traffic.

The bench press

The bench press at the Combine counts the number of repetitions at 225 pounds. It is a measure of strength endurance, not of the maximum weight a player can lift. For linemen, it suggests the ability to handle blocking assignments and the physical demands of the position. For other positions, it is a less direct indicator.

The jumps

The vertical and broad jumps measure the explosive power of the lower body. Teams treat them as indicators of how powerfully a player can push off the ground, which relates to blocking, tackling and breaking on the ball.

The cone and shuttle drills

The three-cone drill and the shuttle measure how well a player can change direction at speed, a skill that matters for nearly every position. Teams often care about these results for defensive backs, linebackers and running backs more than for other positions, because they relate to quick movement in tight spaces.

Position drills

After the standardized tests, players do drills specific to their positions. Quarterbacks throw to receivers, receivers run routes and catch the ball, defensive backs backpedal and break on throws, linemen work through blocking and rushing movements, and kickers and punters demonstrate their skills. These drills are less standardized than the tests, and evaluators watch technique as much as results. A scout may care less about how fast a lineman finishes a drill than about how he moves his feet and uses his hands.

The medical exams

The medical evaluation is the least visible and one of the most consequential parts of the Combine. Players undergo physical examinations by doctors and athletic trainers, and many receive imaging when there is a question about an old injury. The purpose is to give teams a clear picture of each player's health history, so they can decide how much risk they are willing to accept.

Several points apply:

• Teams want to know about previous injuries, how they were treated and whether they are likely to recur.
• The results are made available to clubs through the league's process, so every team can review the same information.
• A medical concern can change a prospect's draft position, sometimes sharply.
• Players are not required to take part in every on-field drill, but they are expected to take part in the medical evaluations.

For a more general overview of how football injuries are tracked and reported, see our guide to reading an NFL injury report. The Combine's medical process happens long before that, but the same idea applies: health information drives decisions.

The interviews

Teams use the Combine to meet prospects in private rooms. These formal interviews are short, often about fifteen minutes, and the league limits how many each team can hold. Within that time, coaches and executives may ask about the player's background, his understanding of football, his decision-making and his goals. Some teams also have players diagram plays on a whiteboard to test their football knowledge.

The interviews provide information that numbers do not. A team may want to know how a player handles pressure, how he explains a mistake or how he talks about teammates. They may also use the conversation to confirm background details gathered elsewhere. The league has also used written and cognitive assessments over the years, and the specific tests have changed. If you want to know what is currently used, check the league's description of the event.

How much does the Combine really matter?

This is the question that matters most, and the honest answer is "it depends on the player."

Most teams build their evaluations from the film of games first. A player who dominates on tape does not become a bad prospect because of a poor forty time. A player who is average on film is not transformed by a great one. Testing numbers are treated as supporting evidence.

Where the Combine matters most is in these situations:

1. Confirming or challenging a scouting opinion. If a scout believes a player is fast, a good time confirms it. If a scout thinks a player is slow, a disappointing time supports the doubt.
2. Separating players who are close on film. When two prospects at the same position grade similarly, an athletic test can break the tie.
3. Identifying players from smaller schools. A player who did not face top competition can use the Combine to show that his skills match those of players from larger programs.
4. Medical clearance. A clean examination removes a question mark, and a worrying one can lead teams to remove the player from their lists.
5. Evaluating character and intelligence. Interviews give coaches a look at how a player thinks.

The Combine is less useful in a few ways. The tests measure athletic traits in isolation, not football performance. A player can train specifically for the drills, which is a reason some scouts refer to a prospect who tests better than he plays. Also, the Combine takes place before the draft and in a controlled setting, so it cannot show how a player handles game conditions.

None of this means the Combine is pointless. It is one input among several. Teams combine it with film, interviews, college workouts called pro days, private visits and background checks. Our article on pro days and private workouts covers the rest of the process.

The perspective of the player

For the players, the Combine is both an opportunity and a pressure test. They are often in their early twenties, and the event can affect their professional futures and their financial prospects. Many spend weeks or months preparing for the specific tests, working with trainers who specialize in Combine preparation. Our guide to Combine preparation for college prospects describes how that works.

Players also make decisions about what to do. Some choose to perform every drill, some skip certain tests and wait to do them at their college's pro day, and some decline to participate in parts of the event. The reasons differ: an injury, confidence in a different setting or advice from an agent. Teams notice these decisions, but a choice to skip a drill is not automatically a negative signal.

How to follow the Combine as a fan

If you want to follow the event, a few suggestions can keep it in perspective.

• Compare within positions. A forty time means different things for a wide receiver and a guard.
• Look at the full picture. A single fast time is less meaningful than a profile that shows speed, agility and strength together.
• Remember the film. Check how a player performed in games before deciding what a number means.
• Be skeptical of "risers" and "fallers." Media reports often exaggerate the effect of a single drill.
• Use our tools. The draft section on the site is a good starting point for following the pre-draft process, and the players index helps you find current NFL players once prospects are drafted.

The short version

• The Combine is an annual event where draft-eligible prospects are measured, tested, examined and interviewed in front of all 32 teams.
• The standard tests are the 40-yard dash, bench press, vertical jump, broad jump, three-cone drill and 20-yard shuttle, followed by position drills.
• The medical exams and interviews are as important to teams as the televised drills.
• Teams use Combine results to confirm or question film evaluations, not to replace them.
• Tests measure athletic traits in isolation, so they should be read alongside game performance and context.
• Dates, formats and the specific assessments change over time, so check the league's announcements for the current event.
