Robert Joseph Cousy (born August 9, 1928) is an American retired professional basketball player. Cousy played point guard with the Boston Celtics from 1950 to 1963 and briefly with the Cincinnati Royals in the 1969-70 season. Making his high school varsity squad as a junior, he went on to earn a scholarship to the College of the Holy Cross, where he led the Crusaders to berths in the 1948 NCAA Tournament and 1950 NCAA Tournament and was named an NCAA All-American for 3 seasons. Cousy was initially drafted by the Tri-Cities Blackhawks as the third overall pick in the first round of the 1950 NBA draft, but after he refused to report, he was picked up by Boston.

After retiring as a player, Cousy published his autobiography Basketball Is My Life in 1963, and in the same year became coach at Boston College. In the 1965 ECAC Holiday Basketball Festival at Madison Square Garden, Providence defeated Boston College 91-86 in the title game, when the Friars were led by Tourney MVP and All-American Jimmy Walker. Providence was coached by Joe Mullaney, who was Cousy's teammate at Holy Cross when the two men were players there in 1947. In his six seasons there, he had a record of 117 wins and 38 losses and was named New England Coach of the Year for 1968 and 1969. Cousy led the Eagles to three NIT appearances, including a berth in the 1969 NIT Championship and two National Collegiate Athletic Association tournaments, including the 1967 Eastern Regional Finals.  Cousy grew bored with college basketball and returned to the NBA as coach of the Cincinnati Royals, team of fellow Hall-of-Fame point guard Oscar Robertson. He later said about this engagement, "I did it for the money. I was made an offer I couldn't refuse." In 1970, the 41-year-old Cousy even made a late-season comeback as a player to boost ticket sales. Despite his meager output of 5 points in 34 minutes of playing time in seven games, ticket sales jumped by 77 percent. He continued as coach of the team after it moved from Cincinnati to Kansas City/Omaha, but stepped down as the Kings' coach early in the 1973-74 NBA season with a 141-209 record.  In later life, Cousy was Commissioner of the American Soccer League from 1974 to 1979. He has been a color analyst on Celtics telecasts since the 1980s." In addition, Cousy had a role in the basketball film Blue Chips in 1993, in which he played a college athletic director. Today he is a marketing consultant for the Celtics, and occasionally makes broadcast appearances with Mike Gorman and ex-Celtic teammate Tom Heinsohn.
