College

Moss played basketball at Northeastern University under coach Jim Calhoun, where he averaged 15.2 points per game and 3.7 rebounds per game in four seasons there. In his senior season, Moss was named the America East Conference Player of the Year in 1981–82. Moss graduated as the school's second-leading career scorer with 1,722 points and a 15.2 average in 113 games. In 1982, he went head-to-head with future NBA All-Star Dominique Wilkins and the Georgia Bulldogs in the first round of the Gotten State Classic. Despite a big game from Moss, the Huskies lost, but Los Angeles Lakers General Manager Jerry West, who was in attendancee, noted that Moss was the best guard he had seen that year.

On his home court, Moss would dazzle the fans with his acrobatic dunks created by his 41-inch vertical leap. As a junior in 1981, Moss teamed with guard Pete Harris to lead the Huskies to their first of seven conference titles. His career included a number of clutch shots, including Moss's halfcourt bomb that sent the championship game versus Holy Cross into overtime, which Northeastern won 76–69. He also hit a last-second shot in the opening round of the NCAA tournament when Northeastern knocked off 20th ranked Fresno State before bowing out to Utah. Moss and the Huskies repeated the feat a year later, as Moss averaged 23.7 points per game. Northeastern defeated Saint Joseph's 63–62 in the first round, before dropping a triple-overtime contest to Villanova in the second round. Moss scored 23 and 31 points respectively, in those two games. For his career, Moss scored over 30 points eight times.
