Toppin's name does not appear in a 2019 mock draft updated four days ago on NBADraft.Net or a BleacherReport.com projection of the first round.
Toppin averaged 14.4 points and 5.6 rebounds in his first season on the court with Dayton as a redshirt freshman. He arrived at UD in June 2017 but sat out the 2017-18 season as an academic redshirt. In the 2018-19 season, he was named to the All-Atlantic 10 first team. He was the first rookie to earn that honor in 20 years. He also became the first Dayton player to win the A-10 Rookie of the Year Award.
