As the most recognized player in Georgetown basketball history, Patrick Ewing frequently has said he owes his development on and off the court to former Hoyas coach John Thompson Jr. Ewing showed his financial appreciation in that regard Monday afternoon by joining with longtime sports agent David Falk to donate $3.3 million toward the construction of the John Thompson Jr. Intercollegiate Athletics Center. Falk has strong ties with Thompson and Ewing, having represented both for decades. The school is set to break ground Sept. 12 on the four-story, 144,000-square foot facility that will be built next to McDonough Gym at a cost of $62 million, all from contributions. The building is to include practice courts and men’s and women’s basketball coaches offices as well as meeting facilities for varsity programs. “Coach Thompson is a very special person in my life,” Ewing said in a telephone interview. “He brought me to Georgetown as a boy and helped me to grow as a man, and I think the gift to the university is something that is very special and very meaningful. It’s blessed with Coach Thompson’s name on it, so I think that it’s something very much worthwhile.” With Ewing as his anchor inside, Thompson directed Georgetown to three Final Four appearances in four years. The Hoyas won their only national championship in 1984 by beating Houston, 84-75. Ewing was named the most outstanding player of that NCAA tournament.
