Detroit rarely had to worry about losing the rebounding battle after drafting Andre Drummond in 2012.The most obvious problem presented by trading Drummond to Cleveland on Thursday was whether the Pistons could continue to hold their own on the boards.Their first home game since the trade wasn’t promising. They were out-rebounded 47-28 in a 95-92 loss Saturday to the New York Knicks. Detroit will look for better results when it hosts the Charlotte Hornets on Monday night.”I think we’ve been spoiled with a guy like Andre, who’s one of the best in the history of the game,” said coach Dwane Casey of Drummond’s rebounding ability. “That’s what he brought to the table. We’ve got to get a mindset of boxing out every time.”Not having Drummond in the middle was especially felt in crunch time when the Knicks were protecting a two-point lead. They grabbed two offensive rebounds to prolong a possession and eventually scored a basket to double their lead.”I didn’t realize it was that bad,” Pistons point guard Reggie Jackson said. “They got after it. Got a lot of offensive boards, second-chance opportunities. We’ve got to figure out a way to rebound as a collective group.”Reserve center John Henson, one of the players the Pistons acquired in the trade, contributed a season-high 12 points in 17 minutes in his Detroit debut. Christian Wood has posted solid numbers in his first two games as Drummond’s replacement in the lineup, averaging 22.0 points and 11.5 rebounds.Even with Drummond, the Pistons endured three frustrating losses to the Hornets earlier this season. Those games were decided by a combined seven points. Charlotte can complete a sweep of the four-game season series on Monday.In the first meeting on Nov. 15, Malik Monk hit a buzzer-beating 3-pointer in a 109-106 Hornets victory. Charlotte eked out a 102-101 win on Nov. 27 when Detroit’s Derrick Rose passed the ball instead of taking a shot in the final seconds. Two nights later, the Hornets held on for a 110-107 triumph when the Pistons missed two 3-point attempts on their last possession.
