Hill made his first start, along with fellow freshman Kendrick Nunn, for the Fighting Illini on February 9, 2014, against Penn State, scoring 11 points and helping the team end an 8-game losing streak. On January 7, 2015, Hill scored a career-high 28 points as a sophomore to lead the Fighting Illini to a win at home against 11th-ranked Maryland when Illinois' leading scorer Rayvonte Rice was sidelined with a broken hand. As a junior, Hill was named one of ten finalists for the 2016 Jerry West Award which is awarded by the Naismith Memorial Basketball Hall of Fame to the best collegiate shooting guard in the United States. In a double-overtime loss to Penn State at the end of the 2015–16 Big Ten Conference men's basketball season, Hill set another career high scoring 39 points. Hill's 39 points were the most since Brandon Paul scored 43 points against Ohio State in 2012 and the seventh most points scored by an Illini player in program history. Following his junior season, Hill became the Illinois basketball player to record 600 points, 200 rebounds and 100 assists in a single season. On Nov. 13, 2016, Hill bested that career mark with 40 points in a 79-64 victory over Northern Kentucky.
