Everyone is searching for "Celtics vs Pistons" today. The 2026-27 NBA season opened with a strange sight: a weekday afternoon game. Boston visited Detroit on Tuesday, October 20, with tip-off at 3 PM ET.
Google Trends logged about 100,000 searches on the matchup in 24 hours, mostly from the United States and Canada. Most fans had the same two questions. Why does the game start so early?
And what is happening with the new-look Celtics?
Why the game starts at 3 PM ET
An NBA afternoon game on a workday feels wrong to many fans. Night games are the norm in the United States. But the league planned this on purpose.
The NBA is experimenting with the early start time. According to ESPN reporter Dave McMenamin, the league wants to see if fans will watch a midday opener. If the audience shows up, the 3 PM start could become a long-standing opening-day tradition.
There is a second reason behind the test. The 2026 World Cup had many afternoon games in the United States. Those games pulled strong interest during the day.
The NBA wants to learn if basketball can do the same. Robert Zeglinski of For The Win asked the same question fans asked. If soccer can win an afternoon American audience, why not the NBA?
The matinee also serves as an appetizer. It opens a full day of basketball. Later tonight, the schedule brings a doubleheader: the 76ers against the Knicks, and the Thunder against the Spurs.
USA Today's For The Win column called the afternoon game the appetizer for that main course.
The game aired nationally on NBC. Fans could also stream it on DIRECTV, Fubo, and Peacock, according to NESN's game-day coverage.
What happened in Detroit
The Celtics walked into Little Caesars Arena as a very different team. This is Boston's first season without Jaylen Brown on the roster since 2015-16. Brown and Jayson Tatum played together every season of Tatum's career. They won a championship together.
They reached five conference finals.
Now Brown wears a 76ers jersey. He joined Philadelphia alongside LeBron James, according to USA Today. Paul George came to Boston in the trade that sent Brown out.
Bleacher Report's live coverage listed George, Tatum, and Jordan Walsh among Boston's starters. That leaves Tatum as the lone star in town. Payton Pritchard, Baylor Scheierman, and Hugo Gonzalez give the Celtics one of the league's deeper benches.
Detroit looks very different from the team Boston is leaving behind. The Pistons are coming off a 60-win season. They kept their core together.
Cade Cunningham, Jalen Duren, and Ausar Thompson all returned. Bleacher Report noted that 80 percent of the group that started 42 games together last season is back. That gives Detroit more continuity than almost any team in the league.
The Pistons were also the East's reigning No. 1 seed. USA Today described them as the home-grown group trying to prove last year was no fluke.
The season preview covers how the East shapes up behind them. Boston's preseason win over Charlotte offered the first look at the post-Brown Celtics.
Why it matters
This game is bigger than one Tuesday afternoon. The Eastern Conference may be the NBA's most interesting story this season. The Knicks enter as defending champions.
They hope to become the first repeat champions since the 2017-18 season. LeBron James and Jaylen Brown joined Joel Embiid in Philadelphia. Giannis Antetokounmpo took his game to Miami.
Tyrese Haliburton returns to Indiana after an Achilles tear. The Cavaliers run back their conference-finalist roster.
For years, the West had the top teams. This season, the East may have the better stories from top to bottom. A 3 PM opener puts that chaos on national television at a time when fans are not used to watching basketball.
The start time itself is a story worth watching. Sports leagues copy what works. The World Cup proved American fans will watch big games in the afternoon.
If this matinee draws strong numbers, every opening day may look like this.
What happens next
The season runs from October into the spring. Boston's experiment starts now. Can one star and a deep bench win in the modern NBA?
Bleacher Report argued last season offered proof. Boston won over 50 games with Brown in Tatum's spot while Tatum sat out most of the year with injury. Now the roles flip.
Detroit has its own question to answer. Winning 60 games was a breakthrough. Staying on top is harder.
Every contender now circles the Pistons on the calendar.
For fans catching up, the guide to watching this NBA season lists every TV and streaming option. Tonight's doubleheader follows this afternoon's opener. The 76ers face the Knicks.
The Thunder face the Spurs. The long season has begun.
