Matthew (Mac) McClung was already an Internet sensation when he decommitted from Rutgers and signed with Georgetown in October 2017. He passed Allen Iverson's state record for most points scored during his senior season at Gate City HS, employing a high flying style that impressed fan and foe alike. The signing also helped end a period of racial stereotyping against Georgetown as a place where white basketball players were allegedly unwelcome or unwilling to attend the school.

McClung was an all-Big East freshman selection in 2018-19, averaging 13.1 points a game with a season high 38 against Arkansas-Little Rock, breaking the Georgetown freshman scoring record set by Victor Page in 1995-96. As a sophomore, he took over the backcourt leadership following James Akinjo's unexpected departure on November 2019, averaging 15.7 points in 20 starts, but suffered through two mid-season injuries and missed the final six games of the season, to which Georgetown lost all six and ended their post-season hopes as a result.

In March, he declared for the NBA draft but maintained his eligibility for a return back to Georgetown. That return was strained, however, during an interview where Ewing declared that McClung was returning to the team for his junior season, only to have McClung's agent deny it. A week later, McClung opted to transfer to Texas Tech in lieu of the NBA draft, the fifth transfer in a tumultuous 2019-20 season. He averaged 15.5 ppg at Texas Tech in 2020-21, and was named the Big 12 Newcomer of The Year. In 2021, McClung declared for the draft but was not selected, signing instead a developmental contract with the Los Angeles Lakers. He saw brief on-court action with the Lakers and the Chicago Bulls before being traded to the Golden State Warriors in 2022. Later that season, he was traded to the Philadelphia 76ers and won the slam dunk contest during its 2023 All-Star Weekend.

McClung left the Hilltop 29th all time in scoring average at 14.2 points a game. He is the highest ranked player by career average ever to transfer from Georgetown.
