PF Ike Diogu was signed to a non-guaranteed deal by the Knicks on Friday. Diogu was the No. 9 pick by Golden State in 2005 and hasn't played in the NBA for nearly two years. The team is looking for depth at backup center and we're guessing if Cole Aldrich's knees can hold up that he'll be that guy, and not Diogu or Josh Powell.
