After a successful four years of college basketball at Ohio University, Cooper entered the 2013 NBA draft but was not selected in the draft's two rounds. As a player at Ohio University, Cooper cracked the top 25 all-time Division I assists leaders list early in his final season and steadily rose up on the record as the season has progressed. He was named the preseason Mid-American Conference Player of the Year by the league's media, a prediction which proved correct when he was named Player of the Year after the regular season. In 2021-22, he led the Israeli Basketball Premier League in both assists per game and steals per game.
