CHAMPAIGN, ILL. ? Dee Brown and Deron Williams put on a three-point shooting clinic for top-ranked Illinois.

Brown scored a career-high 27 points and tied the school record with eight three-pointers, and Williams added 21 points, 12 on three-pointers, in Illinois’ 84-50 victory over Purdue on Thursday night.

The Illini (29-0, 15-0 Big Ten) were 15-of-27 from three-point range, setting a school record for three-pointers in a season with 265 — 10 more than they had in 2001-02.

“They were just unconscious,” Purdue coach Gene Keady said. “That was a tremendous show of shooting ability.”

Brown had 24 points in the first half.

“My teammates screened for me. We had good ball movement,” Brown said. “Once I came off the screens, the rim just looked so (big) and I just continued to follow through and they went in.”

Purdue (7-19, 3-12), playing without injured leading scorer Carl Landry, got 12 points from Gary Ware and 10 from Matt Keifer.

The Illini celebrated their second consecutive conference championship by closing out the Boilermakers by halftime, building a 50-26 lead. Illinois won its 25th straight Big Ten game and 21st in a row at Assembly Hall.

The Illini raced to an 11-4 lead, and Purdue never got closer than five points after that. The Illini had a 21-0 run in the second half and led by as many as 44 points in handing Purdue its fourth straight loss.

Illinois' Dee Brown, right, drives against Purdue's David Teague in the first half. The Illini beat Purdue, 84-50, Thursday at Champaign, Ill., behind Brown's 27 points.

Williams hit four three-pointers and had six assists, including a show-stopping, behind-the-back delivery to Warren Carter for a dunk with 1:04 to go in the first half.

No. 2 North Carolina 91, Florida State 76

North Carolina, which played without scoring leader Rashad McCants for the third straight game because of an intestinal disorder, can clinch the top seed in the ACC tournament Sunday with a home victory against No. 6 Duke.

No. 6 Duke 83, Miami 59

Durham, N.C. — J.J. Redick led Duke with 29 points, and senior Daniel Ewing had the first double-double of his career with 14 points and a career-high 10 assists in his final game at Cameron Indoor Stadium.

Shelden Williams added 14 points and 12 rebounds for the Blue Devils (22-4, 11-4 ACC). Robert Hite 17 points for Miami (16-11, 7-9). Duke will close out its regular season with a rivalry game Sunday at North Carolina.

Taquan Dean added 27 points for Louisville (25-4).

Berkeley, Calif. — Bobby Jones scored 22 points, and No. 10 Washington made a school-record 16 three-pointers to beat California and move within one victory of at least a share of its first Pac-10 title in 20 years.

Jones was 5-of-6 from long range, and the Huskies surpassed the previous school record of 14 set Jan. 29, 1998, at Southern California. It’s the most three-pointers made in the conference this season, and UCLA is the only team to hit 14.
