After redshirting in his first season at Dayton, Toppin built on an excellent freshman campaign in 2018-19 to emerge as one of college basketball's top superstars as a redshirt sophomore. The 6-foot-9, 220-pound forward led Dayton to a 29-2 record while averaging 20.0 points, 7.5 rebounds, 2.2 assists, 1.2 blocks and 1.0 steal in 31.7 minutes per game. Toppin's high-end athleticism and efficiency from three-point range could make him a top-five selection in the draft.
