It's not surprising that the Golden State Warriors are the last remaining unbeaten team in the NBA and closing in on their best start in franchise history.
The Detroit Pistons' strong start is far more unexpected.
The Warriors could be in for a stiff test Monday night when they try to extend the longest home winning streak in franchise history against the Pistons.
Golden State (7-0) is off to its best start since relocating to the West Coast before the 1962-63 season. The Warriors are two wins shy of matching the team record from 1960-61 when they were located in Philadelphia.
Detroit (5-1), however, has as many wins now as it did at Christmas last year as it went on to miss the playoffs for a sixth straight time.
The Pistons' turnaround includes winning all three road games while averaging 108.7 points. It's their best start away from home since opening 5-0 in 2005-06.
They won their latest away contest in stunning fashion Sunday, obliterating a 13-point deficit with a 41-11 fourth quarter to beat Portland 120-103. Reggie Jackson scored 26 of his career-high 40 points in the final period while Andre Drummond added 29 with 27 rebounds.
"I told him (Jackson) it was time for him to take over," Drummond said. "I told him he needed to step it up and take over in this fourth quarter."
Jackson, acquired from Oklahoma City at last season's trade deadline, leads the team with 23.2 points per game after scoring a career-high 14.5 last season.
The guard has averaged 9.5 points in his last four visits to Oakland.
Drummond continues to emerge as more than just a threat on the glass, averaging 20.3 points while adding a league-leading 20.3 rebounds. He's had at least 20 points and 20 boards in three of his last four games.
''Andre's numbers are phenomenal," Pistons coach Stan Van Gundy said. "If he didn't get a rebound the rest of this trip he'd be in the top three or four in rebounding. What he's doing on the boards is just phenomenal. He was just swallowing the ball up down the stretch.''
Drummond has 22 points and 25 rebounds in a 105-98 loss at Golden State on March 11.
That was the Warriors' eighth consecutive win in the series and fifth straight at home.
The matchup is part of a team-record 22-game home winning streak, the league's longest since Denver won 23 in a row from Jan. 2-April 17, 2013.
Golden State has won 41 of its last 42 at home during the regular season, with the only blemish an overtime loss to Chicago on Jan. 27.
The Warriors overcame a season-worst 41.3 percent shooting in a 103-94 victory at Sacramento on Saturday.
"We couldn't get our shots to go in - it happens," interim coach Luke Walton said. "But we found a way to grind it out. We had some wide open looks that wouldn't go down. It was one of those random nights."
That was certainly the case for Stephen Curry, who scored 21 of his season-low 24 points in the second half. He's averaging a league-best 33.9 points per game while connecting on 47.5 percent from 3-point range.
The reigning NBA MVP has been kept mostly in check when facing the Pistons, averaging 17.3 points in the past four meetings. He was limited to nine points on 4-of-15 shooting in the March win.
The Warriors will reportedly have center Andrew Bogut available after he missed six games with a concussion. They may still opt to start Festus Ezeli, who is averaging 10.3 points and 7.0 rebounds.
