In the middle of their longest losing streak of the Erik Spoelstra era, the Miami Heat return home to face the Detroit Pistons on Wednesday night.Miami has lost eight straight games, its worst skid since the 2007-08 season. Spoelstra was hired to replace Pat Riley as the Heat’s coach on April 28, 2008.The Heat (29-39) also has fallen 10 games below .500 for the first time since Feb. 1, 2017.”I’m not going to go into a rant,” Spoelstra said. “We’re all getting tested, including myself. There’s nobody absolved from this. I have not come up with enough answers for this team. I have to do a better job. Our group has to do a better job.”Meanwhile, Detroit (38-31) comes off a 127-81 road win Monday night over the New Orleans Pelicans.”Our intent was great,” Pistons coach J.B. Bickerstaff said. “Execution was great. For a majority of the game, we played to our standard.”Detroit owns seven more wins this season than it managed in the previous two seasons combined.In addition, the Pistons, who are sixth in the Eastern Conference, are on track to end a streak of five straight years without a playoff berth.Detroit hasn’t won a playoff series since 2008, but the Pistons could have a shot this season because of the development of Cade Cunningham.The first overall pick in the 2021 NBA Draft, Cunningham leads the Pistons in scoring (25.6 ppg) and assists (9.3 apg). Both of those are career highs.New president of basketball operations Trajan Langdon and coach J.B. Bickerstaff added veterans Tobias Harris, Malik Beasley and Tim Hardaway Jr. — a Miami native and the son of the NBA Hall of Famer who played five-plus seasons for the Heat.
