CHAMPAIGN—Ever since Illinois fell apart in a 25-point loss Thursday at No. 5 Michigan State, Illini practices have been ”hell,” according to Malcolm Hill. ”Bodies flying and colliding and words that not everybody can hear, from the coaching staff and the players as well,” the quiet junior forward said. Leading scorer Kendrick Nunn missed that game for the birth of his son, and the Illini, by their own admission, were embarrassed on the court.Nunn was back on Sunday, and he and Hill combined for 52 points in an 84-70 win over No. 20 Purdue.Hill scored 30 and Nunn finished with 22 for Illinois (9-8, 1-3 Big Ten), going a combined 17 for 27 from the field. With both hitting shots, Purdue coach Matt Painter said the Boilermakers (14-3, 2-2) didn’t have much of a chance. ”If you can slow one of them down, I thought we would be in pretty good shape,” Painter said. ”We just got beat tonight.” Nunn started slowly but scored 18 points in the second half. That included a nine-point run to open the half that turned a 37-all tie into a 46-37 Illinois lead.Purdue was led by Caleb Swanigan and P.J. Thompson with 12 points each.Illinois big men Michael Finke and Maverick Morgan helped hold Purdue’s two 7-footers, A.J. Hammons and Isaac Haas, to a combined 16 points.Boilermakers forward Raphael Davis fouled out with 1:49 to play. He didn’t score.Nunn said he hadn’t gotten quite as much sleep as he would like since the birth of his son, Kason Lee. The understated junior called it ”a long week.” It took him a half to shake off the rust. He scored four points in the first 20 minutes, but started the second half with the nine-point run, which included a pair of 3-pointers. The first opened the half and gave the Illini a lead they never relinquished.Nunn nailed the second 3 even as he was being knocked to the floor by Dakota Mathias. Nunn hit the free throw that followed, too. ”I had complete confidence in him that he was going to explode in the second half,” Hill said. ”We just feed off each other.” Nunn appeared to foul out with 3:36 left, only to have the officials review the play and call D.J. Williams for the foul on Vince Edwards instead.The crowd let out a relieved cheer.After Morgan sank a short jump shot with 7:24 to play to give Illinois a 65-53 edge, the Illini nursed a double-digit lead until the final buzzer.
