The Detroit Pistons, known as the 'Bad Boys,' dominated the NBA in the late 1980s, winning back-to-back championships in 1989 and 1990. Key players included Isiah Thomas, Joe Dumars, and Bill Laimbeer, supported by a strong roster and coach Chuck Daly.

The Bad Boys era defined the Pistons' legacy in the NBA
The Detroit Pistons are one of the most storied franchises in NBA history, but one era of the team stands out above the rest.
The mid-to-late 1980s was the era of the "Bad Boys," not just in Detroit but all around the league. A Pistons team with a core of point guard Isiah Thomas, shooting guard Joe Dumars and center Bill Laimbeer became the most feared team in the Eastern Conference and led the Pistons to their first two NBA titles in 1989 and 1990. But the Bad Boy Pistons were more than just their three franchise cornerstones.
The franchise also got key contributions (and reputational support) from Vinnie Johnson, John Salley, Rick Mahorn, Dennis Rodman, James Edwards, Mark Aguirre and Adrian Dantley, all led by coach Chuck Daly, by far the all-time winningest coach in franchise history.
This was a Pistons era that got in done on the court, putting up 50-win seasons each year from 1987-91, and also left a stamp as one of the most famous squads in American professional sporting history.
But beyond their personalities, the Pistons teams of the late '80s rolled through the league with a bruising style of play, one that made them one of the best defensive teams in NBA history. And while it was a style that irritated much of the league and opposing fans, the team's hard-nosed play fit the city like a glove, as Detroit rallied around a Pistons team that finally brought NBA glory to the Motor City.
Though they may have been overshadowed by stars Magic Johnson and Larry Bird beforehand, and Michael Jordan afterward, the Bad Boys helped define the NBA for the most memorable stretch of Detroit basketball, with five consecutive trips to the Eastern Conference finals, three consecutive trips to the NBA Finals and back-to-back titles, leaving a championship legacy.
Here's everything you need to know and what made the Bad Boy Pistons such a famous, and infamous, part of NBA history.

Who were the Bad Boys Pistons?
The Bad Boys was the nickname of the Detroit Pistons from the late 1980s to the early 1990s, which encompassed the best stretch of Pistons basketball.
The Bad Boy Pistons went to five consecutive East finals, three consecutive NBA Finals and won two consecutive NBA titles in 1989 and 1990. Their core trio was point guard Isiah Thomas, center Bill Laimbeer and guard Joe Dumars, with critical contributions from guard Vinnie "The Microwave" Johnson and forwards John "Spider" Salley, Dennis "The Worm" Rodman and Rick "McNasty" Mahorn, among others.

In the 1988 Eastern Conference semifinals against an upstart Chicago Bulls team, many fans and writers accused Pistons forward Rick Mahorn of trying to hurt Bulls star Michael Jordan, who won his first of five MVP awards that season. Jordan believed the Pistons, who won the series 4-1 and went on to the NBA Finals against the Los Angeles Lakers, played dirty.
NBA Entertainment first coined the phrase “Bad Boys,” using it as the title of a team video after the 1987-88 season.
When asked about it in the offseason, Pistons star Isiah Thomas embraced the nickname, with members of the Pistons identifying with the style and attitude of the Oakland Raiders teams of the 1970s.
The "Detroit Bad Boys" logo became a popular image throughout the city, with the Raiders-inspired skull and crossbones appearing on T-shirts, hats and flags throughout Detroit.

Though the core players of the Bad Boys team (Isiah Thomas, Joe Dumars and Bill Laimbeer) stretch back to Dumars' rookie season in 1985-86, the Bad Boys nickname didn't come about until two years later after the Pistons lost a heartbreaker to the Los Angeles Lakers 4-3 in the 1988 NBA Finals.
The heyday of the Bad Boys stretch ended in the 1991 East finals, when the Pistons were swept by Michael Jordan, Scottie Pippen and the Bulls.
Thomas, Laimbeer and Dumars stuck around in Detroit for more seasons: Laimbeer and Thomas retired after the 1993-94 season; Dumars stayed with the team until his retirement in 1999. Vinnie Johnson left after the 1991 season, John Salley left after 1992, and Dennis Rodman and Mark Aguirre left after 1993.

Chuck Daly was the coach of the Pistons from 1983-92, encompassing the entire stretch of the Bad Boys era. Known as a stylish dresser and brilliant tactician, Daly coached four NBA teams across 14 seasons, most notably for the Pistons, going 467-271 over his nine seasons in Detroit.
Daly's 467 wins are by far the most in franchise history, with Flip Saunders (2006-08) second on the list with 176. Daly also coached the 1992 U.S. Olympic men's basketball team, known as the "Dream Team," to a gold medal at the Barcelona Summer Olympics.
Daly was twice elected to the Basketball Hall of Fame, once as an NBA coach and another time as the U.S. men's Olympic coach. He died of pancreatic cancer in 2009.
Bad Boys Pistons GM
Jack McCloskey, also known as "Trader Jack," was the Pistons general manger from 1979-91, responsible for virtually every move that constructed the Bad Boy Pistons. His most notable moves were drafting point guard Isiah Thomas No. 2 overall in 1981, hiring coach Chuck Daly, trading for center Bill Laimbeer in 1982, drafting guard Joe Dumars at No. 18 in 1985, drafting forward Dennis Rodman at No. 27 in 1986, trading for forward Adrian Dantley in 1986 and trading Dantley for forward Mark Aguirre during the 1988-89 championship season.
A former NBA player and coach, McCloskey was the most successful executive in Pistons history while making 38 trades in a 10-year period to earn his nickname. He left the Pistons in 1992 and died of Alzheimer's disease in 2017 at age 91.
Bad Boys Pistons defense
The play style of the Bad Boys era of the Pistons was characterized by hard-nosed defense, and it was effective.
The Pistons had a defensive rating (points per 100 possessions) of 104.7 in their first championship season in 1988-89, which was third-best in the NBA. That rating improved to 103.5 in their second championship season in 1989-90, second-best in the NBA.
The defense was anchored in the middle by center Bill Laimbeer and forward Rick Mahorn, who both gained reputations for cheap-shot fouls and intentionally rough play. But Detroit's best defensive player during the Bad Boys era was forward Dennis Rodman, who won Defensive Player of the Year twice in 1990 and 1991, the first Piston ever to do so, and one of only two players in franchise history to win the award (Ben Wallace in 2002, 2003, 2005 and 2006).
Were the Bad Boys Pistons dirty?
Many NBA stars went on the record to call the Bad Boy Pistons dirty, including Hall of Famers Larry Bird and Michael Jordan. The two players who got the biggest reputations for dirty play were center Bill Laimbeer and forward Rick Mahorn, with Laimbeer getting special attention as one of the most hated players in NBA history.
Per research done by FiveThirtyEight, the Pistons between 1986-92 were among the teams with the most technical fouls per game relative to average in that season in NBA history. Whether that constituted as dirty or just strategic is a matter of opinion – though many NBA fans and media considered it dirty.
Bad Boys fights
The Bad Boys logged many notable fights throughout their run in the late 80s and early 90s, but arguably their most famous altercation is their first notable one.
In Game 3 of the 1987 East finals against the Boston Celtics, Pistons center Bill Laimbeer brought Celtics star Larry Bird down with a hard foul, starting a skirmish in the paint that eventually led to both Laimbeer and Bird getting ejected. After being separated, Bird threw a basketball at Laimbeer, leading to Pistons forward Dennis Rodman throwing punches at Bird. The Celtics ended up winning the series in Game 7, but the Pistons broke through a year later beating the Celtics in the 1988 East finals.
The Pistons-Celtics rivalry dates back to 1985, where the Pistons lost to Boston in six games in the East semifinals while establishing themselves as an up-and-coming franchise.
The Pistons and the Celtics met again in the infamous 1987 series, with the series tied 2-2 heading to Boston for Game 5. The Pistons had a one-point lead with seconds left and possession of the ball, but Celtics forward Larry Bird intercepted an Isiah Thomas inbounds pass and passed the ball to guard Dennis Johnson, who laid the ball in for the winning basket. Boston eventually won the series in Game 7, with help from a scary collision between Vinnie Johnson and Adrian Dantley, as the Pistons yet again were unable to win at the haunted Boston Garden.
The Pistons finally broke through against the Celtics in 1988, beating Boston in six games − twice on the road − on their way to their first NBA Finals appearance, where they lost to the Los Angeles Lakers. But by that point, the Pistons had established themselves as the team to beat in the East.

The 1988 East semifinals featured the Pistons and Bulls, with Michael Jordan having earned his first league MVP.
The Pistons devised a plan, known as the "Jordan Rules," with a series of strategies to keep Jordan away from his favorite spots on the floor (and to knock Jordan to the floor if he dribbled into the paint). It worked in the 1988 series and again in the East finals in 1989 and 1990, but Jordan and the Bulls finally broke through in 1991 by sweeping the Pistons in the conference finals, effectively ending the Bad Boys run.
Jordan, for the record, was not a fan of the Pistons play style, especially from big men Bill Laimbeer and Rick Mahorn. He also had animosity for another Pistons player, though for different reasons.
Why does Michael Jordan hate Isiah Thomas?
Michael Jordan revealed during "The Last Dance," the documentary highlighting Jordan's career and centered around the Bulls 1997-98 season, that he hated Isiah Thomas despite respecting his game. Jordan hasn't revealed exactly why, but many suspect it is partly because he blames Thomas for the Pistons walking off the court at the end of the 1991 East finals without shaking hands with the Bulls.
Despite being a strong candidate for the Dream Team, Thomas was left off the roster of the 1992 U.S. men's Olympic basketball team, something Thomas is still upset about. Many suspect Jordan's animosity for Thomas as the reason he was left off the roster.
Many analysts characterize the Bad Boys era of the Pistons as the bridge between two of the most famous eras in NBA history – the rivalry between the Los Angeles Lakers and the Boston Celtics in the 1980s and the Chicago Bulls dynasty of the 1990s. In that way, the Pistons played a big role in the NBA becoming an international cultural force.
But though the Pistons are one of seven NBA franchises to have won back-to-back championships, many don't revere Detroit's Bad Boys run as they do the Lakers in the 1980s, the Bulls in the 1990s, the San Antonio Spurs in the 2000s or the Golden State Warriors in the 2010s. Much of that has to do with the NBA marketing the Lakers, Celtics and Bulls − but not the Pistons.
Many have opinions about the Bad Boys being dirty and bad for the NBA, though the team has gotten a re-examination, especially as many older NBA fans profess nostalgia for the more physical game of the late 1980s and 1990s.
Bad Boys Pistons documentary
ESPN's 2014 "Bad Boys" documentary, directed by Zak Levitt and narrated by Kid Rock, examines the Pistons throughout the 1980s and early 1990s as told by many of the players themselves. It features sit-down interviews with Isiah Thomas, Bill Laimbeer, Joe Dumars, Rick Mahorn, Adrian Dantley, John Salley and Dennis Rodman, among other Detroit-area writers covering the team at the time (including the Freep's own Mitch Albom).
The documentary is available to watch on Netflix and the ESPN app.
