Despite being ultra-productive at Central Dauphin High School in Harrisburg, Pennsylvania, major college programs didn't offer Edmonds because of his lack of size and inability to run away from defenders in the open field. The first-team All-State pick and MVP of the heralded Big 33 All-Star game (Pennsylvania versus Ohio) has shown those big-time programs that he has the talent to excel at any level. Edmonds won the Jerry Rice Award as the Football Championship Subdivision's top freshman in 2014, starting all 14 games and accumulating 1,838 rushing yards (ranking fourth in the FCS) and 23 touchdowns (second) on 294 carries (fourth) while also contributing as a receiver (19-121, one touchdown) and on kickoff returns (24-514). Edmonds garnered second-team Associated Press All-American honors in 2015, as well as Patriot League Offensive Player of the Year, by finishing third in the FCS with 1,648 rushing yards and fourth with 20 rushing touchdowns on 251 totes. Again, he showed versatility with 31 receptions for 383 yards and five scores. His junior season was even more successful, as his cutting ability, supreme balance, and galloping speed allowed him to be named a consensus first-team FCS All-American with 1,799 yards (led FCS with 163.5 yards per game) and 19 touchdowns (ranked third) on 257 carries. Edmonds set an FCS record by averaging 21.1 yards per carry against Lafayette (17-359, four touchdowns). Unfortunately, leg injuries limited Edmonds to seven starts in 2017 (136-577, five touchdowns rushing; 11-129 receiving) and squashed his hopes of setting the all-time FCS rushing record. He was, however, named second-team All-Patriot League for his efforts.
