Ewing, like Chris Mullin at St. John's, would need to load up on high-caliber assistant coaches to help him bridge the gap from assisting in the National Basketball Association to head coaching at the college level.
Georgetown had endured several blows to its future potential after an opening-round loss to St. John's in the Big East Tournament.
Amaker, meanwhile, has led three different college basketball programs as a head coach - Seton Hall, Michigan and, since 2007, Harvard.
If the Hoyas want to keep the head coaching position within the family - Ewing is the next best thing. Georgetown made six more NCAA appearances under Thompson and was never seeded lower than sixth, but each time, the Hoyas were dismissed in the first or second round.
Having been an assistant or associate coach with some of the most respected coaches in recent National Basketball Association history, Ewing has quite the resume already.
The Hall of Fame center, who led the Hoyas to three Final Fours and a national title, has been an NBA assistant coach - now with the Charlotte Hornets - since retiring as a player in 2002, but Ewing has been unable to land the head coaching gig he has long desired. He has been in the mix for a National Basketball Association head-coaching gig in recent years but hasn't landed one. Ewing's son, Patrick Ewing Jr., is now on the Hoyas' staff as director of basketball operations.
The Rams have seen improvement in each of Hurley's five seasons as head coach, and were ranked in the top 25 nationally at the start of the season.
The move is sure to throw the annual NCAA coaching carousel into overdrive as prospective replacements attempt to gain some traction at the Big East program, located in the heart of one of the hot-bed hoops recruiting areas in the country. Texas coach Shaka Smart, who led VCU to a miracle Final Four run in 2011, might not be at Texas next year, and if Georgetown could woo him, he'd be the ideal coach for Georgetown.
Shaka Smart, Texas - This isn't likely going to happen but Georgetown is at least going to call.
This season the Hoyas went 14-18, finishing ninth in the Big East with a 5-13 conference record. Georgetown just finished up a second straight losing season too, which did not help build a case for a return for Thompson III.
The Hoyas had been awaiting the arrival of highly regarded recruit Tremont Waters next season, but the point guard reopened his recruitment process after recently decommitting from Georgetown amid uncertainty regarding the status of Thompson III.
