Jason Kidd became one of the best by making others better. But he looked more burned out than brilliant in the final weeks of the season, and on Monday he decided to end one of the greatest careers for a point guard in league history. “My time in professional basketball has been an incredible journey, but one that must come to an end after 19 years,” Kidd said in a statement released by the New York Knicks. Kidd won an NBA title and two Olympic gold medals, is second on the career list in assists and steals, and was a 10-time All-Star. His retirement comes two days after fellow 40-year-old Grant Hill, with whom Kidd shared Rookie of the Year honors in 1995, announced his retirement.
