Get ready for the Pistons. The Knicks collapsed and lost again to a top opponent Friday night, 108-102 to the Cavaliers, but backed into clinching third seed and a first-round showdown with Detroit. With OG Anunoby, Mitchell Robinson and Josh Hart returning after one-game absences, the Knicks squandered a 23-point early lead early and finished 0-10 against the best three NBA teams — Cleveland, Boston, OKC. That record will become at least the subhead of their regular season, which finishes Sunday in Brooklyn. At best, the Knicks will win 51 games — one more than last season. But for seeding purposes, Friday’s result held no consequences. The Pacers were the only threat to jump the Knicks in the standings, and they were eliminated from consideration after sitting all their starters and getting pummeled Friday against Orlando. The Pistons then locked up the sixth seed by falling to the Bucks, just about 30 minutes before the final buzzer of Knicks-Cavs. After beating New York on Thursday night and winning the regular-season series, Detroit travels to MSG for Game 1 on either April 19th or 20th. It’s the first playoff series between the franchises since 1992 — which was won by the Knicks and headlined by Isiah Thomas versus Patrick Ewing. This season, the Pistons won three of four against the Knicks with Cade Cunningham going off for averages of 30.8 points and 8.3 assists. Still, many of the Pistons have no playoff experience. The Knicks are the more experienced side and favored to advance, regardless of their disappointing finishes the last two nights — Friday especially. Jalen Brunson, playing both games of a back-to-back after Thursday’s defeat, was productive with 27 points. But the other Knicks — Anunoby, Hart, Mikal Bridges — were either ineffective or unremarkable. The only notable inactive was Karl-Anthony Towns, who sat with a sore knee and was replaced in the starting lineup by Mitchell Robinson (33 minutes, eight points, seven rebounds). The Cavaliers had clinched their playoff position and held back their lineup Friday. Donovan Mitchell sat with an ankle sprain, an injury that Cleveland coach Kenny Atkinson acknowledged wouldn’t have kept him out of a more meaningful contest. DeAndre Hunter was also resting. The Knicks’ 0-10 record has served as an indictment on New York’s qualifications as a legitimate contender. But Kenny Atkinson, the Cavs lead man and frontrunner for Coach of the Year, said that’s irrelevant after the weekend. “To me, I wouldn’t make it a thing. You know once the playoffs start, all this means nothing. Clean slate. Playoffs start. All bets are off,” Atkinson said. “We’ve kind of struggled with some elite teams. I don’t kind of buy into that. “The Knicks are an experienced team, well coached, talented as heck. I wouldn’t look too much into that. From a coach’s standpoint, I know Thibs is over there saying, ‘Don’t worry about that. Let’s get ready for the first round.’” That will be the message going forward. Get ready for the Pistons.
