As Georgetown‘s bus made its way to a scrimmage against Virginia on Saturday, Hoyas Coach John Thompson III got a phone call from a familiar number. Team rules dictate that players and coaches aren’t allowed to use their phones during bus trips prior to games, but with Thompson III expecting good news regarding the basketball program’s future, the 10th-year coach made an exception.

On the other end was Paul VI junior Marcus Derrickson, who made Thompson III’s slight infraction well worth it by orally committing to the Hoyas. Derrickson is Georgetown’s first commitment from the 2015 class and comes a night after the highly touted forward attended the school’s Midnight Madness to kick off the upcoming basketball season.

“Coach Thompson was really happy and he said he wanted to shout but he couldn’t because of the rules on the bus,” Derrickson said with a laugh during a Saturday phone interview. “Georgetown is just a great all-around school, from the academics to the basketball. I was always kind of leaning toward there and just talking with the guys and being there Friday, I knew I wanted to be a Hoya.”

In Derrickson, the Hoyas are getting a versatile forward who has a soft touch from the outside, can battle inside for rebounds and points in the paint, and has the size at 6 feet 6 to defend multiple positions. As a sophomore, Derrickson averaged a team-high 12.8 points and 9.3 rebounds in earning first team All-Met honors.

Ranked as the No. 56 overall recruit by ESPN in the 2015 class, Derrickson also held offers from Maryland, Indiana, Miami, N.C. State, Rutgers, Virginia and Villanova, among others.

“What stands out about Marcus is his toughness and competitive spirit,” Panthers Coach Glenn Farello said. “He’s a stretch four that can step out and shoot, but he’s also willing to bang inside. There’s nothing he won’t do to help his team win.”

Derrickson said the Georgetown coaches plan to take advantage of his versatility by having him guard quicker wing players while manning the perimeter and posting up on offense.

“That means I have a lot of work to do, but I see myself as a hard worker,” Derrickson said. “Everybody has talent at the next level, so I like to do the little things that can separate you and that’s why I like Georgetown because I feel like they will always push to get the best results out of their players.”

Come 2015, Derrickson will be teammates with St. John’s senior guard Tre Campbell, who committed to Georgetown in May.
