The Hoyas, led by second-year head coach Patrick Ewing, played their home games at the Capital One Arena in Washington, D.C., as members of the Big East Conference.

Sources: In addition to center Chris Sodom – dismissed from the team at midseason, he had transferred to George Washington – Georgetown had lost four players since the conclusion of the previous season: guards Trey Dickerson, Jonathan Mulmore, and three-season walk-on Ra'Mond Hines had graduated, and, most notably, the team's second-leading scorer, forward Marcus Derrickson, had foregone his senior year of college to enter the 2018 National Basketball Association draft.

Forward Trey Mourning, who had missed the entire 2017–2018 season due to injury, also returned to action in 2018–2019 as a redshirt senior, and the team hoped his perimeter shooting talents would pay dividends on offense.

Most significantly, center Jessie Govan, the team's top scorer, who initially had indicated after the end of the previous season that he, like Derrickson, would leave school to enter the 2018 NBA draft, had changed his mind and decided to play his senior year at Georgetown in 2018–2019.

The arrival of three freshman – guards Mac McClung and James Akinjo and forward Josh LeBlanc – generated particular excitement in the basketball program and among its fans.

[3] After Walker had begun to emerge as an important contributor to Georgetown's frontcourt late the previous season and followed that up with a successful summer in Kenner League play in 2018,[3] observers had speculated that he might start for the Hoyas in 2018–2019.

[3] His departure suggested greater playing time for Josh LeBlanc, Trey Mourning, Kaleb Johnson, and Greg Malinowski in the 2018–2019 season.

[4] At the Big East's media day at Madison Square Garden in New York City on October 25, head coach Patrick Ewing dodged reporters′ questions about his expectations for the 2018–2019 squad,[4] saying only that he was hoping for "a much better year" than in 2017–2018[4] and offering that "everything" about the team would have to get better for it to finish with more than the five conference wins it had the previous season.

[4] With Trey Mourning making the first start of his college career,[5] the Hoyas began their season on November 6 with a victory at Capital One Arena against Maryland Eastern Shore, improving their all-time record against the Hawks to 9–0.

[5] Four days later, the Hoyas began competition in the 2018 Jamaica Classic, the Hoyas′ first appearance in an in-season tournament or showcase event of Patrick Ewing's tenure as head coach.

The Classic was an unbracketed, four-game showcase event, and under its format the Hoyas started by playing a game at Capital One Arena against Central Connecticut State.

The Blue Devils kept the game close, trailing by only three points with four minutes remaining, but Jamorko Pickett sank two three-pointers as part of a 9–0 Georgetown run that clinched the Hoya win.

Ewing, a Jamaica native who had emigrated to the United States at the age of 12, had accepted the invitation to play in the Classic partly because he wanted to show his players his birth country, and because Jagan Moseley's father and Jahvon Blair's parents also had been born on the island.

[11] Two days later, Georgetown bounced back in the next game, in which the Hoyas fell behind former Big East Conference rival South Florida by 11 points early in the second half but pulled out a victory in overtime.

[12] The Hoyas then returned to Capital One Arena for the final game of the Jamaica Classic, building a 22-point lead against Campbell before the Fighting Camels staged a second-half comeback[13] – largely thanks to 45 points by senior guard Chris Clemons, 27 of them after halftime[13] – that brought Campbell to within six points of the Hoyas with 12 seconds left before James Akinjo made four straight free throws to clinch the win for Georgetown.

It was the fourth year in a row the two schools – bitter rivals throughout the 35-season history of the original Big East Conference – had met in non-conference play.

[25] The Hoyas concluded their non-conference schedule with three more home games, facing Appalachian State, Little Rock (coached by Patrick Ewing's onetime New York Knicks teammate Darrell Walker), and Howard.

[42] In the final seconds of the first overtime period, James Akinjo – who finished with 20 points and nine assists – hit three free throws and sank a three-pointer to tie the game at 86–86 as time ran out.

[44] The Hoyas pulled ahead by eight points soon after halftime,[44] but then went five minutes without scoring[44] during a 14–0 Marquette run that gave the Golden Eagles a 57–51 lead with 10:27 remaining in the game.

[43][44] Hauser clinched a 74–71 Marquette victory[44] – the first time the Golden Eagles had won four straight Big East games since 2013[44] – with two free throws with 2.7 seconds left;[44] Mac McClung's half-court desperation shot that followed came after the buzzer.

[54] The win again brought Georgetown to .500 in the Big East at 5–5, equaling their conference win total for the entire year in each of the previous two seasons, but two losses soon followed, a narrow one to Butler at Capital One Arena[55] and a rout at Seton Hall that saw the Pirates take a 20-point lead early in the game in what Ewing described as Georgetown's worst performance in his two seasons as head coach.

[56] In summarizing the loss at Seton Hall, the Associated Press described the Hoyas as "young and exciting,"[56] but added, "Unless they win a bundle down the stretch, or the conference tournament, they should be an NIT team.

Georgetown trailed 28–24 at halftime,[61] before taking the lead in the second half, but Seton Hall redshirt senior guard Michael Nzei tied the game at 59–59 with a jumper at the end of regulation to force overtime.

[61] The Pirates again tied the game at 66–66 when Seton Hall freshman guard/forward Jared Rhoden scored on a buzzer-beating dunk off a fast break at the end of overtime.

[62] However, both their offense and defense let them down;[62] they had their worst shooting performance since the game at Villanova, with only James Akinjo and Mac McClung – with 13 points each[62][63] – scoring in double figures,[62] and their defense allowed four Blue Demons to score in double figures,[62] including 30 points by redshirt senior guard Max Strus[62][63] and 24 by senior guard Eli Cain.

In the quarterfinals, the Hoyas faced Seton Hall, which, like Georgetown had finished at 9–9 and in a four-way tie for third place in the regular season but had been seeded third based on tie-breakers.

Kaleb Johnson started two of the 31 games he played in; he ended the season with a field-goal percentage of 59.3 – 50.0 from three-point range – and with per-game averages of 4.3 points and 2.9 rebounds.

At the end of April, the news broke that after the conclusion of the academic year freshman forward Grayson Carter would transfer to UT Arlington in search of greater playing time.

Seemingly every inspired, dogged performance was followed by a flat-footed one...the Hoyas...face questions, particularly related to coaching, where game preparation and defensive coherence too often were lacking.

"[77] Patrick Ewing viewed the season as another step forward in restoring Georgetown's men's basketball program to the national prominence and success it had once enjoyed, and said that he believed that 19 wins and an NIT appearance represented important progress.
