Georgetown had lost seven players – including its five top scorers – since the conclusion of the previous season. Among those departing were the team's two top scorers of 2016–2017, senior guard Rodney Pryor and junior forward L. J. Peak; Pryor graduated in 2017 after a single season with the Hoyas, and Peak declared for the 2017 NBA draft, foregoing his senior year of college. Starting center Bradley Hayes and power forward Reggie Cameron II graduated in 2017. Junior forward Isaac Copeland had transferred to Nebraska in mid-season, and redshirt junior forward Akoy Agau, after a single season of action with the Hoyas and with two seasons of college eligibility remaining, transferred to SMU during the offseason. Junior guard Tre Campbell left the team after 2016–2017 for personal reasons and, although he remained on scholarship and enrolled at Georgetown for his senior year, he was not on Georgetown's roster and sat out the 2017–2018 basketball season. Another loss was Tremont Waters. Georgetown had lacked a true point guard since the graduation of Markel Starks in 2014, and John Thompson III had attempted to address that by recruiting Waters in the fall of 2016, but Waters had withdrawn his commitment to Georgetown in March 2017 amid the turmoil that surrounded the Georgetown men's basketball program in the aftermath of the 2016–2017 team's losing season. Ewing attempted to re-recruit Waters, but ultimately failed when Waters committed to LSU in early June 2017.
