It’s official: Rasheed Wallace has signed with the New York Knicks.

Also official: The Knicks are really, really old.

The 38-year-old four-time All-Star, who last played in 2009-10 for Boston, joins a 13-man rotation that averages 32 years, 240 days of age, according to STATS, LLC (via the Associated Press). That’s officially the oldest roster in NBA history with five other players 30 or older: Jason Kidd (40 in March), Kurt Thomas (turns 40 on Thursday), Marcus Camby (38), Argentine rookie Pablo Prigioni (35) and Tyson Chandler, who turned 30 on Tuesday.

The Knicks don’t see being aged as any kind of barrier and seem to be aware that this will be a full season, unlike last year’s truncated version because of the lockout. Chandler’s Dallas Mavericks team won the 2011 title with an average age of nearly 30. 

“Obviously, we’ve got some guys a little over that mark,” Chandler said, “but you know what, the guys that we do have are going to bring great veteran leadership and they bring a calmness around the team that we didn’t have before, and it’s only going to benefit us. In order to win in this league, you’ve got to have veterans.”

Coach Mike Woodson seems to think it will make his job easier. We’ll check in with him again in mid-February.

“[Starting his coaching career with a young Atlanta Hawks team] was fun, but I think the fact that I got this veteran team, it’s going to make life a little bit more easier because they’ve been around and they know how to play,” he said. “And I’ve just got to pace them and direct them and put them in the right position.”
