Due to a shortage of players caused by World War II, the Yanks were merged with the Brooklyn Tigers for the 1945 season, and styled as the Boston Yanks. The merged team played four home games in Boston and one in New York. But fans from neither cities cared as they finished with a 3-6-1 record.
When Brooklyn Tigers owner Dan Topping announced his intentions to join the All-America Football Conference in 1946, his NFL team was revoked and all of its players were assigned to the Yanks. After three continuous losing seasons, Collins finally was allowed to move the Yanks to New York and renamed it the New York Bulldogs. They played in the Polo Grounds, sharing it with the football Giants. The team was renamed the Yanks in 1950, when it moved to Yankee Stadium, adding many new players, most of them from defunct All-America Conference teams. Ted Collins sold the team back to the NFL in January 1952. The franchise was awarded to a Dallas group in 1952 and the team name became the Dallas Texans. After drawing very few fans to four games in the Cotton Bowl, the Dallas owners gave up and the NFL took the team over for the rest of the season, during which the Texans had to play all their games on the road. At the end of the season the franchise was disbanded. Finally, in January 1953, the holdings of the defunct Dallas Texans were sold to Carroll Rosenbloom and the franchise was moved to Baltimore, Maryland as the Colts.
The Boston Yanks are the only defunct NFL team ever to have the first overall NFL draft pick. They had it twice in 1944 and 46. Both times they selected a quarterback from the University of Notre Dame: Angelo Bertelli (44) and Frank Dancewicz (46).
