Quinn Cook scored 18 points and Rasheed Sulaimon finished with 13 for the Blue Devils (22-2, 9-2 Atlantic Coast Conference).

The Hoosiers (22-3, 10-2 Big Ten) have won seven of eight and regained a share of the league lead. They are tied with Michigan State.
But it wasn't easy early against Nebraska (12-13, 3-9), which frustrated Indiana by limiting possessions and repeatedly taking the shot clock inside of 10 seconds in the first half. Dylan Talley scored 10 of his 16 points in the first half to lead the Cornhuskers.

The ACC has gone to 18 conference games now because of expansion.

Connecticut 66, No. 6 Syracuse 58: In Hartford, Conn., freshman Omar Calhoun scored 15 points, including three 3-pointers in the deciding second-half run, and Connecticut beat Syracuse in the last scheduled game between the national powers.
Syracuse (20-4, 8-3 Big East) will play next season in the Atlantic Coast Conference while Connecticut will stay in the realigned Big East, although the Huskies (17-6, 7-4) could be enticed to head to another conference if asked.
Their last game was a close one until Calhoun started the run with a 3 that gave the Huskies the lead for good at 45-42 with 9:49 to play.

It appeared the Fighting Irish (20-5, 8-4 Big East) might cruise to victory until the Blue Demons (10-14, 1-10) used an 11-1 run to take the lead. Notre Dame then rallied to force overtime - four days after beating Louisville in five overtimes.
