Training Pitt Bulls?

Midway through the 1931 season, Philadelphia's representative in the NFL, the Frankford Yellow Jackets, went bankrupt and ceased operations. After more than a year of searching for a suitable replacement, the NFL awarded the dormant franchise to a syndicate headed by former Yellow Jackets owners Bert Bell and Lud Wray, in exchange for an entry fee of $2,500. Drawing inspiration from the insignia of the centerpiece of President Franklin D. Roosevelt's New Deal, the National Recovery Act, Bell and Wray named the new franchise the Philadelphia Eagles. (Neither the Eagles nor the NFL officially regard the two franchises as the same, citing the aforementioned period of dormancy; furthermore, almost no Yellow Jackets players were on the Eagles' first roster. Some observers, however, believe the two teams should be treated as one.) The Eagles, along with the Pittsburgh Steelers and the defunct Cincinnati Reds, joined the NFL as expansion teams.
