Plumlee finished 9 of 12 while Sulaimon was 9 of 13 with six 3-pointers twice as many as his previous high, and four in a 3-minute span of the first half.
Dez Wells and Charles Mitchell both had 13 points for the Terrapins (15-5, 3-4). They have lost four of six and were denied their first victory at Cameron Indoor Stadium since 2007 and first win over a No. 1 team since '08.
Villanova 75, No. 3 Syracuse 71 (OT) • Ryan Arcidiacono hit the tying 3-pointer with 2.2 seconds left in regulation, and James Bell hit consecutive 3s in overtime to send Villanova to its second win over a Top 5 team this week.
Arcidiacono's 3-point attempt to tie with about 25 seconds left in regulation was off the mark. Syracuse's Michael Carter-Williams missed the front end of a 1-and-1 and JayVaughn Pinkston of the Wildcats grabbed the rebound.
Bell missed a 3-pointer and Mouphtaou Yarou grabbed the offensive rebound. Syracuse decided not to foul, giving Yarou time to kick it out to Arcidiacono. He let go a leaner from just beyond the 3-point line to tie the game at 61, force overtime and send the crowd into a frenzy.
No. 18 N.C. State 91, North Carolina 83 • Lorenzo Brown had 20 points and 11 assists to help No. 18 North Carolina State end a 13-game losing streak in the long rivalry.
Freshman T.J. Warren added 19 points for the Wolfpack (16-4, 5-2 Atlantic Coast Conference), who beat the Tar Heels for the first time in nearly six years.
