In over 100 years of Georgetown basketball, John Colrick holds the mark for the fewest wins as a head coach, just five.
A 1929 graduate of Notre Dame, Colrick was born in Ireland, one of the few Fighting Irish players to have actually been born there. His family emigrated to Newark, NJ, where he was a star athlete at St. Benedict's Prep, graduating in 1925. Traveling to South Bend, Colrick played three years as a football player under coach Knute Rockne and was a rare three-sport star at Notre Dame, earning nine letters over three years of play in football, baseball, and basketball. It was Colrick, the starting left end, who was benched at a key moment of a football game on Nov. 10, 1928, when subtitute receiver Johnny "One Play" O'Brien caught the winning touchdown pass in a 12-6 ND win over Army, immortalized as the game where Rockne exhorted his team to "win one for the Gipper".
In 1929, Georgetown officials asked Rockne for a recommendation to replace outgoing football coach Lou Little. Rockne's suggestion was ND ssistant coach Tommy Mills, who brought Colrick and three other recent grads as his assistants, and Colrick served three years as an assistant football coach at the Hilltop.
Following the resignation of head basketbal coach Bill Dudack in 1930, Mills (now the athletic director) installed Colrick as basketball coach for the fall of 1930. The loss of four starters was too much for the 23 year old coach and his team, and Georgetown finished 5-16. Colrick opted to return to football, and the Hoyas then picked up Fred Mesmer, himself only a year removed from the varsity, as Colrick's replacement.
Colrick found himself out of a job altogether in 1932 as Mills quit as head coach midway through the 1932 football season, Colrick returned to New Jersey and coached sports at Seton Hall for two seasons, compiling a 8-22 record in basketball and an 11-6 record in baseball.
Little is known about John Colrick following his tenure at Seton Hall. He died in Newark in 1948 at the age of 40, with contemporary reports ranging from a heart attack to a terminal illness. He is buried in an unmarked grave in North Arlington, NJ.
