Football Basics
Start here. The vocabulary every other term builds on.
- Down
- One play. The offense gets four downs to gain 10 yards; make it and the count resets to 'first down'. '3rd & 4' means third down, four yards still needed.
- First down
- Gaining the 10 yards needed to earn a fresh set of four downs. Moving the chains. The basic unit of a sustained drive.
- TouchdownTD
- Getting the ball into the opponent's end zone. Worth 6 points, plus the try for one or two more. The stat every scoring column counts.
- Field goalFG
- A place kick through the uprights, worth 3 points. The fallback when a drive stalls in range.
- Extra point / two-point conversionXP / 2PT
- The try after a touchdown: a short kick for 1 point, or one play from the 2-yard line for 2.
- Turnover
- Losing possession to the defense. An interception or a lost fumble. The stat most correlated with losing.
- Snap
- The exchange that starts every play, from the center back to the quarterback. Snap counts measure how much a player was actually on the field.
- Drive
- One continuous possession. The series of plays from getting the ball until scoring, punting or turning it over.
- Line of scrimmage
- The invisible line where the ball sits before the snap. All yardage on a play is measured from here.
- Red zone
- Inside the opponent's 20-yard line, where drives are expected to end in points. Red-zone usage is a strong touchdown predictor.
- Punt
- Kicking the ball away on fourth down to pin the opponent deep instead of risking a failed conversion.
Positions
The four offensive skill positions YunoBall tracks stats for.
- Quarterback
- Leads the offense and throws (or occasionally runs) the ball on most plays. Judged mainly on passing yards and touchdowns against interceptions.
- Running back
- Takes handoffs and runs with the ball; modern backs also catch passes out of the backfield, which matters a lot in PPR fantasy scoring.
- Wide receiver
- Lines up wide and catches passes downfield. Production shows up as targets, receptions, receiving yards and receiving touchdowns.
- Tight end
- A hybrid blocker/receiver who lines up next to the offensive line. Scored like a receiver, but usually with fewer targets.
Passing Stats
Everything a quarterback question can ask about.
- Passing yards
- Yards gained on completed passes. The headline stat for quarterbacks. A 4,000-yard season is a strong year; 5,000 is historic.
- Passing touchdownPASS TD
- A completed pass that scores a touchdown. Credited to both the passer and the receiver.
- InterceptionINT
- A pass caught by the defense. A turnover charged against the quarterback. The classic risk stat weighed against touchdowns.
- Completions / attemptsCOMP/ATT
- Passes caught by the intended receiver versus passes thrown. Together they give completion percentage.
- Sack
- The quarterback is tackled behind the line of scrimmage before he can throw. Counted against the offense as lost yardage.
Rushing & Receiving Stats
The ground game and the catch game.
- Rushing yards
- Yards gained running the ball. 1,000 rushing yards in a season is the traditional benchmark for a lead running back.
- Rushing touchdownRUSH TD
- A touchdown scored on a running play.
- CarryATT
- One rushing attempt. Yards per carry (yards ÷ carries) measures a runner's efficiency.
- ReceptionREC
- A caught pass. In PPR fantasy formats every reception is worth a point on its own, whatever the yardage.
- Receiving yards
- Yards gained on caught passes, measured from the line of scrimmage to where the receiver is downed.
- Receiving touchdownREC TD
- A touchdown scored by the player catching the ball.
- Target
- A pass thrown a player's way, caught or not. Targets measure opportunity. A high-target player has a stable role in the offense.
- Fumble (lost)
- The ball carrier drops the ball. It's only a turnover. A 'fumble lost'. When the defense recovers it.
Fantasy Football
The scoring language behind the Fantasy page and the assistant's start/sit calls.
- PPR (point per reception)PPR
- A fantasy scoring format that awards one point per catch on top of yardage and touchdown points. YunoBall's fantasy numbers are full-PPR.
- Fantasy points
- A player's real stats converted to a single score: roughly 1 point per 10 rushing/receiving yards, 1 per 25 passing yards, 4-6 per touchdown, minus turnovers. Plus receptions in PPR.
- Points per gamePPG
- Fantasy points divided by games played. A fairer measure than season totals when comparing players who missed time.
- Start / sit
- The weekly lineup decision between two rostered players. The assistant weighs production rate, PPR floor and offense environment rather than raw totals alone.
- PPR floor
- The safety net receptions provide: a player who catches 6 balls banks 6 points even on a quiet yardage day. High-catch players have high floors.
- Boom/bust
- A volatile scoring profile. Players who rely on touchdowns for most of their points swing hard week to week. Big booms, ugly busts.
- Waiver wire
- The pool of unrostered players in a fantasy league, claimed in a priority order between games.
Seasons & Games
How the NFL calendar is sliced everywhere on this site.
- Regular seasonREG
- The 18-week, 17-game schedule (16 games before 2021) that decides playoff seeding. Stat leaderboards default to regular-season numbers.
- PostseasonPOST
- The playoffs: Wild Card, Divisional and Conference rounds, then the Super Bowl. YunoBall groups all four rounds under one postseason label.
- Super BowlSB
- The league championship game between the AFC and NFC winners. The last game of the postseason.
- Week
- One slate of games. Regular-season weeks run 1-18; postseason rounds continue the numbering, which is why a Super Bowl can appear as week 21 or 22.
- Bye week
- A team's scheduled week off during the regular season. Players score nothing that week. The classic fantasy trap.
- Streak
- Consecutive results of the same kind, newest game backwards: W3 means won the last three, L2 means lost the last two.
- Point differential+/-
- Points scored minus points allowed. A quick read on how dominant (or lucky) a team's record really is.
- Win percentagePCT
- Wins plus half-credit for ties, divided by games played. The number standings are sorted by: .750 beats .688.
Players & Careers
How players enter the league and earn their roles.
- Rookie
- A player in his first NFL season. Rookie stats set career baselines. A 1,000-yard rookie receiver is a genuine event.
- NFL Draft
- The annual seven-round selection of college players, worst teams picking first. Where most stars enter the league.
- Depth chart
- A team's ranking of players at each position. The starter, the backup, and so on. Climbing it is how a player earns snaps and stats.
- Free agentFA
- A player whose contract has expired and can sign with any team. The offseason's player-movement market.
- Veteran
- An experienced player past his rookie contract. 'Vet' production tends to be steadier. Less upside, higher floor.
League Structure
How 32 teams organize into the standings you see.
- ConferenceAFC / NFC
- The league's two halves. The American and National Football Conferences, 16 teams each. Their champions meet in the Super Bowl.
- Division
- Four-team groups within each conference (e.g. NFC West). Division rivals play twice a year, and each winner is guaranteed a playoff spot.
- Franchise
- The team as an organization, across relocations and renames. YunoBall folds history forward. Oakland Raiders stats live under today's Las Vegas Raiders.
