The Worst Record in NFL History, Measured Three Ways
The most losses any NFL team has taken in one season is 16, by the 2008 Detroit Lions and the 2017 Cleveland Browns. The lowest winning percentage is .000, which those two share with at least five other teams since 1940, because a winless season produces the same percentage whether it ran eleven games or seventeen.
Those two answers pull in different directions, and most articles on this question quietly pick one without saying which. Here is the honest version: “worst record in NFL history” resolves differently depending on the metric, and the metric only makes sense once you fix the era.
The three answers
| Measure | Record holder | Value |
|---|---|---|
| Most losses in a season | 2008 Lions, 2017 Browns | 16 |
| Lowest winning percentage | Seven teams since 1940 | .000 |
| Worst point differential (post-merger) | 1976 Buccaneers | -287 |
| Longest losing streak | Chicago Cardinals, 1942-45 | 29 games |
The point-differential answer is the one that best matches what people usually mean when they say “worst,” because it measures how badly a team was beaten rather than how many chances it had to lose. Tampa Bay’s expansion year produced 125 points scored and 412 allowed across only 14 games. No post-merger team has been worse per game or in total.
Why .000 is a tie and not a ranking
A winning percentage of zero is zero. The 1942 Lions went 0-11, the 1976 Buccaneers went 0-14, and the 2008 Lions went 0-16. All three are .000. Ranking them by percentage is impossible, which is why “most losses” exists as a separate record — and why a longer schedule makes a worse-looking record easier to produce, not harder.
Teams sitting at .000 since 1940:
| Season | Team | Record | Season length |
|---|---|---|---|
| 1942 | Detroit Lions | 0-11 | 11 games |
| 1943 | Chicago Cardinals | 0-10 | 10 games |
| 1944 | Brooklyn Tigers | 0-10 | 10 games |
| 1944 | Card-Pitt | 0-10 | 10 games |
| 1976 | Tampa Bay Buccaneers | 0-14 | 14 games |
| 2008 | Detroit Lions | 0-16 | 16 games |
| 2017 | Cleveland Browns | 0-16 | 16 games |
Two more teams finished winless without reaching .000: the 1960 Cowboys at 0-11-1 and the 1982 Colts at 0-8-1. Both are covered in our complete list of NFL winless seasons.
The tie rule changes the arithmetic
Before 1972 the NFL calculated winning percentage as wins divided by wins plus losses, discarding ties entirely. From 1972 onward a tie counts as half a win and half a loss.
That single change reshuffles the bottom of the record book:
| Team | Record | Pre-1972 method | Modern method |
|---|---|---|---|
| 1960 Cowboys | 0-11-1 | .000 | .042 |
| 1982 Colts | 0-8-1 | .000 | .056 |
| 1-15 teams (many) | 1-15 | .063 | .063 |
Under the old method Dallas’s expansion season was officially .000, tied with every other winless club. Under the modern method it is .042 — worse than any team that ever won a game, but not the worst possible. The 1982 Colts land at .056, which is still below the .063 that a 1-15 season produces. So the two lowest non-zero winning percentages in league history both belong to teams that never won.
This is the kind of detail that makes “worst record” answers disagree across sources. Neither number is wrong; they are computed under different rules.
Season length changes what the record even means
The NFL has played 10-, 11-, 12-, 14-, 16- and 17-game regular seasons. A 16-loss season was structurally impossible before 1978 and a 17-loss season was impossible before 2021.
| Era | Schedule | Worst possible record | Worst actually achieved |
|---|---|---|---|
| 1940s | 10-11 games | 0-11 | 0-11 (1942 Lions) |
| 1961-1977 | 14 games | 0-14 | 0-14 (1976 Buccaneers) |
| 1978-2020 | 16 games | 0-16 | 0-16 (2008 Lions, 2017 Browns) |
| 2021-present | 17 games | 0-17 | 2-15 (2023 Panthers) |
Nobody has gone 0-17. Five seasons into the 17-game era, the worst record is the 2023 Carolina Panthers’ 2-15, a .118 winning percentage. Carolina also set a stranger record that year: they never held a fourth-quarter lead in any game, and both of their wins came on field goals as time expired.
The strike-shortened 1982 season is the other structural outlier. Nine games is a short enough sample that a bad team can miss a win the way a coin can come up tails nine times without anything unusual happening. Comparing 0-8-1 to 0-16 without saying that out loud is the same error as comparing a 66-game basketball season to an 82-game one.
Worst record versus worst team
The 2017 Browns lost every game and were outscored by 176 points. The 2023 Panthers won twice and were outscored by 180. By margin, Carolina was the worse team. By record, Cleveland was.
Point differential is the more stable measure of quality across a season, which is why the 1976 Buccaneers keep showing up at the top of “worst ever” lists despite playing two fewer games than the 0-16 teams. Their minus-20.5 per game is a full five points worse than Detroit’s 2008 mark.
Records reward or punish a team for how the close games broke. Margins do not. Both are real; they answer different questions.
The mirror of the record this site is built on
One team has finished a full season, playoffs included, without losing: the 1972 Dolphins. Seven have finished a season without winning. The gap in those counts is the whole point — the same compounding that makes going 17-0 statistically brutal makes going 0-16 relatively reachable, because the roads to the bottom of the league are structural and the road to the top is not.
For the near-misses in the other direction, see the NFL teams that almost went undefeated. For the deep dive on the worst of them, the anatomy of Detroit’s 0-16 season covers how a team loses all sixteen while playing five of them within a touchdown.

Frequently asked questions
Which team has the lowest winning percentage in a season that included a win?+
No team with a win holds it. The lowest non-.000 winning percentage belongs to the 1960 Dallas Cowboys at .042 (0-11-1) and the 1982 Baltimore Colts at .056 (0-8-1), both from ties rather than wins. The lowest for a team that actually won a game is .063, the 1-15 mark reached by more than a dozen teams.
Why do the 1960 Cowboys show a .000 percentage in some record books?+
Because before 1972 the NFL ignored ties entirely when computing winning percentage. Dallas's 0-11-1 was officially .000 at the time. Recalculated under the modern half-win rule it comes to .042, which is why two sources can list the same team differently without either being wrong.
Has a team ever gone winless and still had a top-10 player?+
Yes. Calvin Johnson tied for the NFL lead with 12 receiving touchdowns for the 0-16 Lions in 2008, and Myles Garrett was the first overall pick and a rookie contributor on the 0-16 Browns. Neither made the Pro Bowl that year. Individual quality does not prevent a winless season because football outcomes are decided by units rather than by single players.
What is the worst record a team has taken into the playoffs?+
7-9, achieved twice: the 2010 Seattle Seahawks, who won the NFC West and then beat the defending champion Saints in the wild card round, and the 2020 Washington Football Team. Both are products of division-winner seeding rather than overall record.
Does a losing streak count as a record separate from a season record?+
Yes, and they rarely line up. The longest losing streaks span seasons, so no single-year record captures them. The Chicago Cardinals' 29 straight losses from 1942 to 1945 crossed four seasons and includes a year in which the franchise was merged with Pittsburgh.
