After escaping with an improbable victory over Penn State on Saturday, Purdue's men's basketball players joked and laughed through their postgame interviews. In the dark hallways under Welsh-Ryan Arena on Tuesday, the somber Boilermakers spoke with regret about a 63-60 double-overtime loss to Northwestern. Purdue emerged victorious from similarly perilous late-game situations earlier this season. This time, it was Drew Crawford, Tre Demps and the Wildcats who prevailed in the clutch and ended the Boilermakers' three-game losing streak. "We had a lot of chances to put the game away and we just came up short," Purdue sophomore guard Ronnie Johnson said. "They were able to knock some shots down at the end of the game, some tough shots, and we just have to live with it." Crawford and Demps scored 19 points apiece. Demps hit a game-tying 3-pointer late in regulation and another late in the first overtime. Crawford made a pair of baskets to help push the Wildcats to a game-changing four-point lead midway through the second overtime. Purdue's players were already in Evanston on Tuesday when news broke of a campus shooting in which one student killed another. A moment of silence was held before the game, and Northwestern students who painted their chests to spell out "Stand With Purdue" in purple and white letters stood in the bleachers on the Wildcats' end of the floor. But the Boilermakers said the incident did not distract from their focus for the game. Instead of taking a four-game winning streak into Saturday's home game against Wisconsin and separating itself from the bottom of the Big Ten, Purdue instead must regroup from a frustrating missed opportunity. "We just have to look at it that we have another chance Saturday to get back at it and try to get that 'W,' " said Purdue senior guard Terone Johnson, who scored 16 points on 4 of 17 shooting.
