According to a source close to the Friars program, the 6-foot-6, 230-pound McDermott, also a standout on the gridiron, committed to Providence on Monday night.
McDermott was a seldom-used role guy on the Gauchos last summer, but he averaged 19.8 points, 10 boards and 8 assists as a senior at New Rochelle.
Providence assistant Steve Demeo was on McDermott early, but it appeared as though the Blue Devils would have a legitimate shot of landing him when he took a visit to Durham earlier this month.
McDermott has a terrific body, is athletic, has leadership skills, is humble, unselfish and plays hard. Add court vision and versatility to the mix and it's a wonder why it took so long for coaches to notice him.
McDermott put up 30 points and 11 boards in a January victory against Texas-bound C.J. Miles and Skyline High.
