Northern Illinois (13-6, 7-10) led 25-24 at halftime after Aaric Armstead's layup.

Markel Starks added 17 points and a career-best 11 assists, and Jabril Trawick had 15 points for the Hoyas (17-12, 8-9), who shot 54 percent and advanced their cause as a bubble team for the NCAA tournament. They also still have a chance to be one of the six teams in the overhauled, 10-team Big East to get a bye in next week's conference tournament.
McDermott scored 16 of his 22 points in the second half, making a series of 3-pointers that helped cut a 16-point deficit to five. The Bluejays (23-6, 13-4) have lost two straight and are left with an outside chance at winning the regular-season title in their first year in the conference.
