With Miami Heat stars LeBron James and Dwyane Wade in the stands, the Hurricanes put on another show at home, building margins of 9-0 and 44-27 to improve to 11-0 at home, where each of their past four wins have been by at least 22 points.
Such success is unprecedented for the Hurricanes (19-3, 10-0 Atlantic Coast Conference), who set a school record for ACC victories in a season with eight games to go.
Reggie Bullock had 14 points for the Tar Heels (16-7, 6-4).
NO. 12 MICHIGAN ST. 78, PURDUE 65
WEST LAFAYETTE, Ind. — Branden Dawson scored 20 points and Keith Appling added 17, leading Michigan State past Purdue.
The Spartans (20-4, 9-2 Big Ten) have won nine of their last 10 and will have at least a share of the league lead regardless of the result Sunday when No. 1 Indiana visits No. 10 Ohio State.
Purdue (12-12, 5-6) was led by Terone Johnson with 20 points and Ronnie Johnson with 15, but it wasn't enough to avoid a fourth loss in five games or a fifth straight loss in the series.
Michigan State opened the second half on a 12-5 spurt to take a 43-28 lead. Purdue never got closer than 11 after that.
NO. 13 KANSAS ST. 79, IOWA ST. 70
MANHATTAN, Kan. — Rodney McGruder scored 22 points and Angel Rodriguez added 20 as Kansas State knocked off Iowa State to take sole possession of first place in the Big 12.
Korie Lucious led the Cyclones (16-7, 6-4) with 16 points and reserve Tyrus McGee had 15.
The Wildcats (19-4, 8-2) held a slim 33-32 lead at the break in a game that remained close most of the way. With 9:10 remaining, Kansas State led 61-52.
In response to a pair of Iowa State baskets, Gipson and Rodriguez both scored and put the Wildcats up 65-55 — the first double-digit lead of the game.
Consecutive 3s by Lucious pulled the Cyclones within seven but Iowa State could get no closer.
NO. 14 BUTLER 59, GEORGE WASHINGTON 56
WASHINGTON — Rotnei Clark scored 14 points and Butler nearly blew a 17-point lead, going the last 7½ minutes without a field goal, before holding on for a victory over George Washington.
