Five sophomores – guard Tre Campbell, small forward L. J. Peak, and forwards Isaac Copeland, Paul White, and Trey Mourning – returned for 2015-16, as did the team's only junior, power forward Reggie Cameron, and senior center Bradley Hayes. Senior guard Riyan Williams, the son of former Georgetown great Reggie Williams, also made the team as a walk-on for the third straight season. The most significant returnee was guard D'Vauntes Smith-Rivera, the team's top scorer for two straight seasons. After the conclusion of the previous season, Georgetown had announced that Smith-Rivera had decided to forego his senior year of college and enter the 2015 National Basketball Association draft, a sudden move that surprised observers, who had not ranked him highly as a National Basketball Association prospect. Smith-Rivera did not hire an agent, however, and, with his final year of college eligibility therefore intact, he decided a week later to withdraw his name from the draft pool and return to Georgetown for his senior year. Speaking publicly about his decision three weeks after that, Smith-Rivera had explained that he initially had decided to enter the NBA draft out of an abundance of confidence in himself and comfort with his abilities as a player, but that his parents had convinced him that returning to Georgetown and completing his education was a wiser choice.
