The Detroit Pistons are on the verge of doing something only six NBA teams have ever done – and it's a group of teams they don't want to join.
Should the 1-seed Pistons lose their first-round series to the 8-seed Orlando Magic, Detroit would become the seventh 1-seed in NBA history to lose a playoff series to an 8-seed. But if you dig deeper, Detroit's potential "accomplishment" gets even more ignominious.
Of the first six 1-seeds to fall to 8-seeds, two of them lost in a best-of-five series – the NBA switched to a best-of-seven format for the first round in 2003. Two of those teams were missing their best player for the majority of the series. And of the six losers, only two won at least 60 wins in the regular season.
The 2025-26 Pistons, meanwhile, are playing in a seven-game series with a healthy roster having won 60 regular-season games. In other words, there is no good excuse the Pistons can lean on for losing this series.
Whether it would be the most embarrassing series loss in NBA history is up for debate. But while you're preparing to make your case, let's recap the six times a 1-seed has fallen to an 8-seed in the NBA playoffs.

The NBA expanded its playoff format to 16 teams in 1984, allowing 8-seeds to participate in the postseason for the first time. It took a full decade for a team to finally break through, the 8-seed Denver Nuggets in 1994.
The 63-win Seattle SuperSonics, featuing Shawn Kemp, Gary Payton and Detlef Schrempf, were favored to win all throughout the series, especially after going up 2-0 in the best-of-five series. But the Nuggets pulled out the next two games at home before taking a 98-94 overtime victory in Seattle, becoming the first 8-seed to ever win a playoff series.
It took a few years for the next one to break through.
The 1998-99 Miami Heat are a bit of an outlier, since they played in a lockout-shortened season (finishing with a 33-17 regular-season record) and got the 1-seed thanks to a tiebreaker with the Orlando Magic and Indiana Pacers. Still, the 8-seed Knicks pulled out a surprise victory in five games, with guard Allan Houston's running floater with seconds left in the win-or-go-home Game 5 sending the Knicks to the next round.
The Knicks continued to make history, beating the Atlanta Hawks and Indiana Pacers in their subsequent series to become the first 8-seed to make the NBA Finals. And though they lost to a San Antonio Spurs team just beginning a dynastic run, that Knicks team had arguably the most exciting playoff run an 8-seed team has ever experienced.
One of the most beloved underdogs in NBA history, the 2006-07 "We Believe" Warriors entered March six games under .500 before finishing the season 16-5, squeaking into the playoffs as a 42-win team and facing the 1-seed Dallas Mavericks, who had just completed a franchise-best 67-win campaign behind an MVP campaign by Dirk Nowitzki.
But the Warriors overcame the odds, stealing Game 1 in Dallas and then winning all three of their home games in front of a raucous crowd at Oracle Arena in Oakland. Golden State then fell to the Utah Jazz in five games in the second round, but for one series they put together arguably the greatest first-round upset in NBA playoff history.
The 2010-11 Memphis Grizzlies were one of the toughest 8-seeds of all time, winning 46 regular-season games with a loaded roster of stars, including Zach Randolph, Marc Gasol, Rudy Gay, Tony Allen and Mike Conley. Still, few expected them to compete against a 61-win San Antonio Spurs team still in the middle of its dynastic run.
But that's exactly what they did, with the "Grit-N-Grind" Grizzlies grinding down the Spurs in six games – the first playoff series win in franchise history (in its 16th season). And though they lost to the upstart Oklahoma City Thunder in the second round, the Grizzlies' win against the Spurs kicked off the most successful run in team history.
This one comes with a pretty large asterisk, since the story of the series wasn't the 8-seed Philadelphia 76ers taking down the 1-seed Chicago Bulls, but league MVP Derrick Rose tearing his ACL in Game 1 and missing the rest of the series. After that injury, Chicago's playoff hopes were basically done (as was the highest level of Rose's career).
The Bulls still put up a fight, however, winning Games 1 and 4 and losing the series-clinching Game 6, 79-78, on Andre Iguodala's free throws in the hectic final seconds.
Of all the 1-seeds falling to 8-seeds in NBA playoff history, this one is arguably the most excusable.
The 1-seed Milwaukee Bucks have a built-in excuse for losing a seven-game series to the 8-seed Miami Heat, as their star Giannis Antetokounmpo missed Games 2 and 3 with a back injury and played Games 4 and 5 hurt. But the Bucks also lost to a team on a historic hot streak, with the 8-seed Heat riding Jimmy Butler all the way to the NBA Finals.
Butler averaged 37.6 points in the 2023 first-round series win to get some revenge for the 2021 first-round sweep at the hands of the Bucks. His Game 5 performance on the road is one for the ages with 42 points, including the tying alley-oop to beat the fourth-quarter buzzer in a 128-126 overtime win.
