On the court, Blaney scored 1,012 career points, was a two-time All-New England selection and served as co-captain during the 1960-1961 season, when the Crusaders went 22-5 and finished third in the NIT. But his contributions to Crusader basketball after his playing days ended are more impressive. After a professional career playing with New York and Philadelphia, Blaney turned to coaching. He began with stints at Stonehill and Dartmouth, but beginning in 1972 he coached the Crusaders for 22 seasons until 1994, winning 357 games and leading Holy Cross to eight post-season appearances. He was the New England Coach of the Year in 1976, and the MAAC Coach of the Year in 1990. He was inducted into the New England Basketball Hall of Fame in 2003.
