LAS VEGAS — So far this summer, the road for Jalen Duren and the Detroit Pistons has been a bumpy one. Duren and the Pistons have yet to come to an agreement in restricted free agency on a new contract, while suitors for Duren have dwindled. What was once a multi-lane highway for Duren’s services is now looking more like a two-way street.For Duren, staying in Detroit looks like the best way forward.Finances will likely play the biggest role, as the 22-year-old was “underwhelmed” with the Pistons’ first offer, as The Athletic first reported nearly two weeks ago.Duren broke out in his fourth NBA season with the Pistons. His 19.5 points per game were a career high, and his 10.5 rebounds and 65 percent from the field were both the second-most he averaged in the league. His 21.3 percent usage rate last season was a career high and ranked in the 87th percentile for bigs, per CleaningTheGlass. His 184 unassisted made field goals last regular season were a career best as well.But in the playoffs, Duren was abysmal.The team that makes the most sense for LeBron JamesEsfandiar BaraheniHe dropped to 10.2 points and 8.5 rebounds on 51.4 percent in his 14 postseason games. Duren couldn’t generate quality offense for himself or any of his teammates the way he did during the regular season.Duren’s frustration with negotiations led him to seek sign-and-trade opportunities. The big man met with the Los Angeles Lakers and Sacramento Kings, but the Lakers went on to sign restricted free agent Walker Kessler and Detroit reportedly wasn’t interested in moving Duren for Kings center Domantas Sabonis.The Memphis Grizzlies and Brooklyn Nets are the only two teams in the league with cap space as of Friday, but neither is expected to compete for championships for the foreseeable future.
