The 6-10, 220-pound Rabb played parts of two seasons with Memphis, averaging 5.7 points and 4.3 rebounds in 85 games (18 starts.) Rabb is not with the Knicks in San Antonio. The Knicks backed out of a verbal agreement with Wilkes because of an undisclosed illness. The Post reported they hadn’t ruled out signing Wilkes later in the year. The Knicks’ other two-way signee is Kadeem Allen.
