Patrick Ewing has been fired as basketball coach at Georgetown after the latest in a series of rough seasons for the school he led to a national championship as a player in the 1980s. The school announced Thursday it would begin searching for a successor. Ewing’s last game was an 80-48 loss to Villanova in the Big East Tournament on Wednesday. He went 75-109 in six years, including 7-25 this season. Ewing also presided over a 29-game Big East losing streak that was the longest in league history. His tenure included just one winning season and zero victories in the NCAA Tournament.
