NEW YORK - Jason Kidd retired Monday from the NBA after 19 seasons, ending one of the greatest careers for a point guard in league history.

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. But he struggled badly in the playoffs for the New York Knicks shortly after turning 40 and decided to walk away with two years and more than $6 million left on the deal he signed last summer.

"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 Knicks. "As I reflect on my time with the four teams I represented in the NBA, I look back fondly at every season and thank each every one of my teammates and coaches that joined me on the court."

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.

Kidd went on from there to have big impacts on every team he joined. He led the longtime-losing Nets to two NBA Finals in 2002-03, helped the Dallas Mavericks win the 2011 title, and was on the first Knicks team to reach the second round of the playoffs since 2000.

He averaged 12.6 points, 8.7 assists, 6.3 rebounds and 1.93 steals in a career that also included a stop in Phoenix. Kidd had numerous ways to make his mark on games, ranking third on the career list with 107 triple-doubles while finishing third all-time in 3-pointers made, despite being considered a poor outside shooter when he came into the league.

"Jason's value to the Knicks and the National Basketball Association cannot be quantified by statistics alone," Knicks general manager Glen Grunwald said. "Everyone here in New York saw firsthand what a tremendous competitor he is and why Jason is considered to be one of the best point guards, and leaders, the game has ever seen."
