Collins was a four-year letterman for coaches Pat Dye and Ed Emory and was the Pirates' all-purpose yards leader for three consecutive seasons. As a junior in 1979, he led the team in rushing with 1,130 yards, which helped him earn First-Team All-South Independent honors. That season he helped the Pirates set team records for rushing, rushing yards per game, total offense, total offense per game and points per game. He currently ranks ninth on the school's single-season and career rushing charts and its career points scored list. His 100-yard kickoff return against Florida State in 1980 still ranks as the longest in school history. The New England Patriots selected Collins in the second round of the 1981 National Football League (NFL) Draft.
