Team owner Ted Collins, who managed singer and television show host Kate Smith (1907–1986) for thirty years, picked the name Yanks because he originally wanted to run a team that played at New York City's old Yankee Stadium.

Because of a shortage of players caused by World War II, the Yanks were temporarily merged with the erratic founding APFA member Dayton Triangles' franchise, then known as the Brooklyn Tigers, for the 1945 season, and styled as just the Yanks with no home city named.

The merged team played four home games in Boston and one in New York and finished with a 3–6–1 record.

When Brooklyn Tigers owner Dan Topping announced his intention to join the newly established rival professional football league, the All-America Football Conference (AAFC), in 1946, his NFL franchise, which was a founding APFA member that he had moved from Dayton, Ohio in 1929, was revoked and all of its players were assigned to the Yanks, with the original Triangles legacy being carried on by this group.

They had it twice, in 1944 and 1946, selecting quarterbacks from Notre Dame, Angelo Bertelli and Frank Dancewicz, both Massachusetts natives.
