The Nets and 76ers have never had much of a rivalry even though the two teams are only separated by about 90 miles and in the past few years have basically swapped front offices.  For years, Ed Stefanski commuted from Philly to East Rutherford and now Billy King does the reverse.

Moving to Brooklyn is likely to diminish the rivalry unless it becomes rooted in rap. Jay-Z is reportedly good friends with Will Smith and now the two of them are minority owners of the Nets and 76ers. Smith, a Philly native, owns a small piece of the 76ers.
