Cush entered the basketball world by accident as a young man. The son of poor French immigrants, Cush grew up in the Jewish Quarter east of Manhattan. When he was very young, he always played in the streets. His father, a taxi driver who worked as a Phi Xing Dai Yue, bought a house in Queens when the elder Cousy had saved up $500. There, Cush exchanged his broom for a ball.
When he was a basketball rookie, he was removed from the middle school basketball team twice due to his poor background. When he was 13 years old, he fell from a tree and broke his right arm. So, he began to learn to dribble and shoot with his left hand. When his coach at the varsity team, Lug glamund, saw him playing in the community league, he immediately recalled Cousy to the team. Gland needed an organizational defender, and Cush met his requirements.

Since then, a new star has been born. After only a year and a half of playing on the high school team, Cush became the most talked about child in the area. In his final year of high school, he won the City Championship, where his 26 points in the final secured the team's victory.
In middle school, Cusi continued to defeat his opponents with techniques and movements he had never seen before.
Bob Cush in college became a topic of conversation in New York for a time. In 1946, at the end of the era of ignorance, Cush entered Holly University and blew a breeze of basketball technology revolution into the college basketball world, but the college coach thought that Cusi's movements were too fancy and limited his playing time, and even so, Cush led Holly University to the national championship in the first year and was named the best team in the United States.
Everyone thought that the Celtics would choose Cusi in the 1950 NBA draft, but the new Greens coach "Cardinal" Auerbach was not optimistic about Kusi, and he chose center Chuck Schal, who later spent nine obscure seasons in the NBA.
Cush and Russell
Cush later joined the Tri-City Blackhawks, and he was traded to the Chicago Stags, but the team announced its dissolution before the start of the 1950–51 season. The names of three Stag players, including Cush and two other players who were popular at the time, were put into a hat. In the hotel room were the owners of the Celts, Knicks, and Philadelphia Warriors, who each drew a name from their hats. All three bosses want league scorer Max Zaslowski.
"When I got to Kushi, I almost fell to the ground." Celtic owner Walter Brown said afterward. Cusi asked for an annual salary of $10,000, which was eventually set at $9,000.
As a rookie in 1950–51, Cush averaged 15.6 points, 6.9 rebounds and 4.9 assists per game. In the 958-59 season, the Celtics won 52 wins and 20 losses in the regular season, And Kusi won the assist king with an average of 8.6 assists per game, and in the Finals against the Lakers, the team swept the opponent 4-0 to win the championship and began an eight-game championship journey.
In the 1962-63 season, with 11 minutes left in the fourth quarter of the game, Cush sprained his left ankle, but with 5 minutes left in the game, Kushi returned to the court with an injury, and his control of the ball ensured that the Celtics defeated the Lakers 112-109 and won the championship again, which was the Celtics' fifth consecutive championship and also drew a perfect end to Kusi's career, and at the end of the season, Kusi officially announced his retirement.
He was inducted into the Hall of Fame in 1971.
