In the moments after his Georgetown team was blown out by Villanova on Wednesday night at Madison Square Garden, Patrick Ewing solemnly walked through the handshake line.
Dressed in a black sweatsuit, Ewing greeted one player after another, then turned and walked by himself off the court toward the locker room. It was a walk he had made hundreds of times, first as a college player at Georgetown, then as an N.B.A. star with the Knicks. Wednesday, though, was different: The Hoyas’ 80-48 drubbing by the Wildcats in the first round of the Big East tournament, yet another loss in yet another lost season, might have been his final game as Georgetown’s coach.
