チーフ・ジェイ・ストロンボー
Valentine began working on a casual basis for the World Wide Wrestling Federation (WWWF), then owned by Vincent J. McMahon, in November 1978. Managed by The Grand Wizard, he was given the gimmick of a methodical wrestler who broke the legs of all his opponents, including Chief Jay Strongbow. In February 1979, he wrestled then WWWF Heavyweight Champion Bob Backlund to a one-hour time-limit draw at Madison Square Garden.
