It was, unwittingly, the center of the New York professional sports universe in 1975.

The official home of both Major League Baseball's Mets and AFL-then-NFL football's Jets since 1964, Shea Stadium was always a busy venue. But when the football Giants and baseball Yankees found themselves displaced by extensive renovations to their shared Bronx home of Yankee Stadium, Shea instantly became Mecca for Gotham sports fans – hosting all four teams over the course of their respective 1975 seasons.

The Giants, of course, had already started their wayward journey away from the Bronx in 1973, when plans were announced for a brand new, state-of-the art facility in the Meadowlands of East Rutherford, New Jersey to open in time for Big Blue's 1976 season. After two miserable seasons at New Haven, Connecticut's Yale Bowl (winning only one of 12 games there), the Giants were wooed by New York mayor Abe Beame to play one last season back inside the city limits before absconding for good across the Hudson.

The Yankees, meanwhile, set up temporary shop at Shea beginning in the spring of 1974 – the first of two seasons the Bronx Bombers would play "home" games there while awaiting their new digs, also to open in 1976.

Thus, for one crazy 1975 season, all four New York teams – the Mets, Jets, Yankees, and Giants – called Shea Stadium home. Four teams, 175 games, 3,738,546 fans, and one stadium – the only time in professional sports history that two baseball teams and two football teams shared the same facility in the same year.

Brett Topel (When Shea Was Home: The Story of the 1975 Mets, Yankees, Giants, and Jets) joins the pod to discuss the highlights – but mostly lowlights – of one of the oddest years in New York City sports history.
