4. Grant Riller, Charleston
Guard, 6-foot-3, 22 years old
Charleston guard Grant Riller is an insanely productive scorer who has averaged at least 18.0 points per game for three years in a row. Among all seniors, Riller might have the highest ceiling because he can create his own offense which will help him stand out early and often. The guard ranked seventh-best among all Division I players in total isolation scoring, per Synergy, averaging 3.2 points per game on these opportunities when tasked with creating his own looks. He is also an incredible interior finisher and shot 107-of-152 (70.4 percent) within five feet of the basket in 2019-20. That was second-best among all NCAA players who are 6-foot-3 or shorter and had at least 100 attempts in this zone, per Bart-Torvik.
