Bill created the first fantasy baseball and fantasy football leagues that we know of. In the late 1950s, Bill started the S.T. SIHRT – Superior Tile Summer Invitational Homerun Tournament. In August 1963, he had the first draft of the GOPPPL – the Greater Oakland Professional Pigskin Prognosticators league. He also dabbled in fantasy golf in the late 1950s. The GOPPPL’s purpose was to promote the Raiders and the AFL.
Winkenbach was also a 10% limited partner of the Oakland Raiders.
Bill, as we know it, is the father of fantasy sports.
