The manager of the D.C. Armory has formulated a "confidential" blueprint for a 2-year-old organization, the U.S. Boxing Association, to stimulate professional boxing in the United States and conduct national tournaments in 10 weight classes, it was learned yesterday.

The proposal by Willie E. Johnson would reduce the role of major television networks in promoting individuals rather than the sport. It would also take control of championships from warring international governing groups.

Johnson proposes that the U.S. Boxing Association, formed two years ago by Chuck Davey, chairman of the Michigan Athletic Commission, "take a bold step and issue a proclamation declaring itself as the official governing body for boxing in the U.S." The USBA also would seek official recognition by Congress.

The 15-page proposal outlines championship tournament in 10 weight classes, involving eight boxers in each class. Tournaments would be held in different cities during the first week in February. The Draw would be based on USBA rankings.

Each fighter would be guaranteed at least $5,000. The champion would be guaranteed $32,000 and boxers would share in gate and television receipts.

The television package would be negotiated by the USBA, instead of individual promoters.

The USBA would rank the boxers, adhere to a seeding formula for pairing for such a tournament, govern selected promoters who must post a $32,000 bond and insist that telecasts promote the competition rather than individuals.
