Key takeaways
- Football fields three separate personnel groups — offence, defence and kicking units — which is why the position list is long and why a roster is really several rosters.
- Positional importance and positional value are different questions: the second one asks how hard a slot is to fill, not how much it matters on a given play.
- The offensive and defensive lines are graded as units, so the weakest member sets the ceiling rather than the average member setting the level.
- Positions whose contribution never shows up as a counting statistic are the ones drafters routinely underrate.
- A draft simulator scores how well a roster fits together under its own internal rules; it is not a forecast of anything that happens in real football.
The board offers you a slot marked OT and three names under it. You have already spent picks on the positions you understand, the ones whose contribution you could describe to somebody at a bus stop. Now you are being asked to pay for a player whose entire job is to make sure something does not happen.
This is the part of football drafting that separates people, and it is not really about football knowledge. It is about knowing what each slot on a team sheet is for, and therefore what it costs you to get it wrong.
Football is three rosters wearing one uniform
Most team sports ask the same players to attack and defend. Football does not. The group that plays offence, the group that plays defence, and the group that plays on kicking downs are largely different people with different builds, different training and different skills.
That single structural fact explains almost everything else about the sport, including why the position list runs to twenty-odd names while other sports manage with five or six. It also explains why football roster building feels harder than it looks: you are not assembling a team, you are assembling three of them, and a surplus in one does nothing for the others.
The arithmetic that never changes
Eleven players per side, always. What varies is how you distribute them.
A common offensive grouping looks like this:
five offensive linemen + one quarterback + one running back + one tight end + three wide receivers = eleven
Swap a receiver for a second tight end and you get a heavier grouping better suited to running. Swap the running back out for a fourth receiver and you get a lighter one built to throw. The eleven is fixed; the mix is a decision, and it is a decision that tells the defence something.
Defences work the same way. One common arrangement:
four defensive linemen + three linebackers + two cornerbacks + two safeties = eleven
Take a linebacker off and add a defensive back and you have traded run defence for coverage. Every defensive alignment you will ever hear named is some version of that trade.
The offence, position by position
The offensive line: centre, guards, tackles
Five players whose job is to control the space in front of the quarterback and open the space in front of the runner.
- Centre snaps the ball and typically identifies the defensive front, which makes it the position with the most thinking attached. A centre who reads a front wrongly gets four other linemen blocking the wrong people.
- Guards line up immediately either side of the centre. Their work happens in a crowd, at close quarters, against powerful interior linemen. Good guard play is mostly invisible; bad guard play arrives in the quarterback's lap almost instantly.
- Tackles play the outside edges of the line, and this is where the line gets exposed. A tackle is regularly left alone against the quickest pass rusher the opposition has, in open space, with nobody nearby to help. The tackle protecting the side the quarterback cannot see is the most demanding of the five.
The important thing about the line is that it is graded as a unit and it fails as a unit. Pressure only has to get through in one place. Four excellent linemen and one poor one do not average out to a good line; they produce a line with a known address that the defence will visit repeatedly.
Quarterback
The quarterback touches the ball on essentially every offensive snap, which makes it the one position where a rating gap is felt continuously rather than situationally.
What the position actually requires is decision-making under a deadline: read what the defence is doing, decide where the ball goes, and deliver it before protection breaks down. Arm strength is the part that shows up in highlights; the reading is the part that decides seasons.
Running back
Three jobs, and drafters usually only count the first. A back carries the ball, catches passes out of the backfield, and blocks blitzing defenders. That third job is the one that gets quarterbacks hurt when it is done badly.
Running back is also the position where the surrounding cast matters most. A back running behind a poor line and a back running behind a good one are being asked different questions, which is why production at this position travels less well than production anywhere else on the field.
Tight end
The hybrid. A tight end lines up attached to the offensive line and is expected to block there, then run routes and catch passes like a receiver.
Its real value is ambiguity. When a genuinely two-way tight end is on the field, the defence cannot tell from the personnel grouping whether a run or a pass is coming, and has to prepare for both. A tight end who can only block, or only catch, hands that information back for free.
Wide receivers
Receivers are usually split into outside and slot roles. Outside receivers work near the sideline against a defender with the boundary as an extra defender; the job rewards speed and the ability to win a contested ball. Slot receivers work in the congested middle, where the job rewards quickness, route craft and the willingness to catch in traffic.
Both get open. They get open differently, and a roster of three players who all get open the same way is easier to defend than the sum of their ratings suggests.
The defence, position by position
The defensive line
Split roughly into interior and edge.
Interior linemen occupy blockers. The best of them command two, which mathematically frees a teammate somewhere else. This is the clearest example in the sport of a contribution that never appears next to the player's own name.
Edge defenders rush the passer from outside. The reason they are prized is subtle: a front that generates pressure with four rushers lets the other seven defenders drop into coverage. A front that has to send extra rushers to generate the same pressure is playing coverage a man short. Pressure without blitzing is the single most valuable output a defensive front can produce.
Linebackers
Linebackers sit behind the line and have to be good at contradictory things — filling running lanes, dropping into coverage, and occasionally blitzing.
The middle linebacker is usually the defensive equivalent of the centre: the one making the calls and setting the front. Outside linebackers vary enormously by scheme, which is why the label alone tells you less than any other on the team sheet.
The secondary: cornerbacks and safeties
Cornerbacks cover receivers, either tracking a man or holding a zone. It is the most isolating job on the field. Every mistake is public, immediate and usually large.
Safeties play deepest and function as the error-correction layer. One is typically deployed as a free defender with responsibility for the deep middle; the other plays closer to the line and contributes against the run. A defence with only one of those two types is a defence that is either soft against the run or thin over the top.
Special teams
Kicker, punter, long snapper, holder, returners and the coverage units that run down the field with them.
These positions have low volume and high leverage: they are involved rarely, and when they are involved the outcome swings a lot. Drafters ignore them because they are boring and because there is no way to make them exciting. They are also the cheapest place on a roster to lose games you had otherwise won.
Turning all of that into draft-board behaviour
Knowing what a position does is step one. Knowing what it is worth to you is step two, and it is a different question.
Importance and value are not the same thing. Importance asks how much a position affects a play. Value asks how hard the slot is to fill from the pool in front of you. A position can be enormously important and still be poor value if competent options are everywhere, and a position can be modest in importance and expensive in value if the pool is thin.
Find your worst unit, repeatedly. Because the lines fail as groups, a football roster is capped by its weakest unit rather than lifted by its best one. Every time you are choosing between improving something already good and repairing something bad, football pushes the answer further towards repair than the other drafting sports do. The football draft simulator guide works through what that means under a salary cap and in a no-refresh format.
Distrust lists sorted by production. Counting statistics credit the player at the end of the sequence. The blocker, the double-teamed tackle and the safety who prevented the play from being called are all invisible on that list, and they are exactly the players a well-built roster is quietly full of.
Take the scarce thing first. If a position group is deep, waiting costs you very little. If it is thin, waiting is how you finish the draft with the hole that defines your season.
| Group | Positions | What you are really buying |
|---|---|---|
| Offensive line | C, G, T | Time for the quarterback and space for the runner |
| Backfield | QB, RB | Decisions per snap, and carries plus protection |
| Receiving | WR, TE | Ways to get open, and ambiguity before the snap |
| Defensive front | DT, DE / edge | Pressure that does not cost you coverage |
| Second level | LB | Run fits, coverage underneath, disguise |
| Secondary | CB, S | Isolation coverage, and the error-correction layer |
| Kicking units | K, P, LS, returners | Rare events with outsized swing |
What the simulator is doing with all this
When you finish a roster in 20-0 Football Draft & GM Mode and the season simulator returns a record, that record is the game's own assessment of how well your eleven-by-three fits together. It is scoring roster construction under the model's internal rules.
Three limits are worth stating plainly. The players are fictional and generated inside the game, so nothing in the result describes or forecasts any real league, team or athlete. The record is a score, not a prediction, and the useful question after one arrives is which of your picks it is disagreeing with. And the perfect unbeaten run the game is named for is deliberately hard rather than the expected outcome of a competent draft — the gap between your record and perfection is the information you drafted for.
The game's Gridiron IQ challenges test the same skill from the other direction: reading a completed team sheet and spotting which group will let it down. If your drafts keep producing records you did not expect, that is usually where the gap lives.
Where to go next
Positional thinking transfers across sports, and it changes shape as the lineups get smaller. Hockey compresses the same ideas into six slots, which the hockey positions guide covers, and soccer expresses them as shape rather than personnel, which is the subject of the soccer formations guide. If what you want is a roster puzzle you can finish on a train, the short-session manager games guide is the more practical read.
