If the name of the city is in the team name, then the team
belongs to that city. For example, the San Francisco 49ers'
stadium is in Santa Clara, but they belong to San Francisco.
Teams like the Golden State Warriors or
Arizona Cardinals are given to the city where
the stadium is located, or the nearest major city that also hosts
other major sports teams.
In the unusual WW2-cases where multiple teams merged into one team temporarily, such as the '44 Carpets or the '43 Steagles, they were given to the city in which they played their opening home game.
Also, all of the Minnesota teams should be labeled Minneapolis/St. Paul, but that would make the tables too large. Sorry, St. Paul.
Read all about that here.
A drought starts or is extended only if your city goes an entire year without any of the teams winning a championship. There are no partial droughts within a year.
For MLB and MLS seasons, which are entirely contained in one year, the championship belongs to that year.
For NBA and NHL, where we can refer to a season longhand, we refer to both years, such as the 1995-96 Chicago Bulls. But when referred to shorthand, or when we are allocating the championship to a specific year, we always use the later year, which is the year the playoffs were in. For example, we consider the 1995-96 Chicago Bulls and the 1996 Chicago Bulls to be the same team, and that team won the championship in 1996.
For NFL, we always refer to each team by one year, and that year is the year the season started and when most of the regular season games are played. So for example, we would refer to a team as the 1985 Bears even though they played multiple games in 1986. And for consistency's sake, we also refer to the '85 Bears as having won the NFL championship in 1985, even though the Super Bowl was actually played in 1986.
This is a little confusing because it isn't consistent, but this is the widely accepted way to refer to the teams in various leagues for sports fans. For NHL and NBA, we track a season by the later year, and for NFL seasons we track a season by the earlier year.
For most sites, these distinctions would just be a matter of cosmetics, but for our site these distinctions do matter for various rankings, for example in terms of drought lengths by city or lists of multiple championships in the same season.
It is very easy to assume that the last undefeated team is equivalent to
the team that starts the season with the most wins/ties (which is the
incorrect assumption many other sites make), but there are
situation where this shorthand isn't entirely accurate.
Conceptually, the idea of the last undefeated team is simple: at some point in time, one team is undefeated, and every other team has at least one loss, and therefore that team is the last undefeated team.
Most of the time, the last undefeated team is the team that started the season with the most wins, such as the extreme and obvious cases of the '72 Dolphins or 15-16 Warriors.
But take the example of the 2003-04 NBA Season, where the Lakers started 5-0 before their first loss, while the Sonics only started 3-0 before losing. At face value you'd assume the Lakers were the last undefeated team, but let's consider the situation on November 8th, 2003. Due to the way the schedule worked out, the Lakers had already played 6 games, and the night before had suffered their first loss and had just fallen to 5-1. The Sonics, only having played 3 games, were still 3-0, and wouldn't lose until the next night. Therefore, clearly the Sonics were the last undefeated team, because there was an entire day where they were undefeated and nobody else in the league was, regardless of the fact they'd played fewer games. For seasons when this happens, we note it with an asterisk and if you hover over it, you'll see the details.
This could be taken to the extreme of seeing when games actually ended down the minute, but for the purpose of the last undefeated metric, we assume all games on a given day happened at the same time. For the NFL, we assume all games which happened in a given week happened at the same time as throughout the site we use the week as the primary timestamp of NFL games.
For basketball, only NBA league-years are counted, dating back to the first season.
For hockey, only NHL league-years are counted, dating back to the first season.
For baseball, only MLB league-years that had a modern world series are counted, starting in the 1903 season (the year of the first modern world series). However, we still track games back to the beginning of the modern era (1885 and onwards) for things like winning streaks and championship droughts, they just don't count for the Champ score.
For football, we count NFL league-years starting in 1920, and AFL league-years starting in 1960. The AFL and NFL merger was completed in 1970, so from 1970 onward, only NFL league-years are counted. AFL championships do not count for the champ score, and because of this, AFL-only seasons do not count towards championship droughts.
For MLS, we include every year in league history starting in 1996.
All pages related to games are updated every day, so all stats related
to individual games (streaks, head to head records, biggest wins, etc)
should be at most one day out of date.
The champ score updates 5 times a year, at the conclusion of the NFL, NBA, NHL, MLB and MLS seasons.
MLS used to not be in the champ score at all! But due to the rapid rise of soccer in the USA, thanks to Men in Blazers and others, we've added in MLS with a 1/3rd weight in the champ score calculations.
