The formation of the "New York-New Jersey Basketball Seven" was announced at a press conference on June 30, 1975.

It was described by Rutgers athletic director Fred Gruninger as "...not a formal conference or league, but merely an association of schools agreeing to play each other on a regular basis."

Rutgers head basketball coach Tom Young stated that "The main objective of a Metropolitan league is for the fans to enjoy the games even more than they have in the past.

I think league competition just naturally creates more interest and it's great for basketball in this area."

As of March 1980, the NY-NJ 7 continued to be mentioned as an active association with teams preparing to play each other in the 1980-81 season, but references to it seem to disappear after that point.
