While the Jets won their first three games with Ewbank as coach, his first several years were unsuccessful. The team, meanwhile, had to deal with numerous logistical issues stemming from its second-tier status among New York's sports teams. The Jets switched stadiums from the Polo Grounds in Manhattan after the 1963 season to the newly built Shea Stadium, but shared Shea with baseball's New York Mets. Concerned about possible damage to the stadium's turf, the Mets would not allow the Jets to practice at Shea, forcing the team to hold practices at the Rikers Island jail complex. The Jets posted a 5–8–1 win–loss–tie record each year between 1963 and 1965.
