The Boston Celtics announced today that the club has signed point guard Rajon Rondo to a multi-year contract extension.  Per team policy, terms of the deal were not disclosed. Several media outlets had reported the deal to be five years and at least fifty five million.

“We are extremely pleased to be able to extend Rajon’s contract,” said Celtics President of Basketball Operations, Danny Ainge.  “We believe that he is one of the elite point guards in the NBA and has a tremendous future ahead of him.”

Rondo, a 6’1” guard, is currently leading the NBA in total assists (47) and is second in assists per game (11.8) through four games this season. The former Kentucky Wildcat is also leading the NBA in total steals (10).  Last season, Rondo became the second Celtic to post three triple-doubles in a postseason joining Larry Bird when he posted three during the 1985-86 postseason.   During the 2009 postseason, Rondo just missed averaging a triple-double when he finished with an average of 16.9 points, 9.7 rebounds and 9.8 assists in 41.2 minutes per game.

“I would like to thank the Celtics ownership, Danny Ainge, Doc Rivers, my teammates and the Celtics organization for all of their support over the years,” said Rondo.  “I would also like to thank my family, friends and fans.  I’m ready to do everything I can to bring banner 18 to Boston.”

During his second season as a professional Rondo helped the Celtics win their 17th NBA Championship with averages of 10.2 points, 4.1 rebounds, 6.6 assists and 1.73 steals per game.  Rondo became just the third starting point guard in the past 30 years to have won an NBA championship at the age of 22 or under joining Tony Parker and Magic Johnson.
