Philadelphia's Greasy Neale and Pittsburgh's Walt Kiesling would be co-head coaches because each coach refused to be demoted. This led to several problems: the first being that the two men hated each other. Secondly, Kiesling's own players did not like him; so asking the Eagles players to like him was too much to ask. However, Neale took advantage when Kiesling was delayed en route to camp which was held at St. Joseph's College in Philadelphia. By the time Keisling arrived, Neale already had the offense learning the T-formation, which was all the rage in those days because of its success in college football that was used by Frank Leahy at Notre Dame and by Red Blaik at Army. This conflict led to Neale serving as the team's offensive coordinator; while Kiesling served as the defensive coordinator. They would then split head coaching duties. According to defensive back Ernie Steele, the situation between the two coaches got so bad that Kiesling and Neale walked off the field after a heated argument during practice before a game. They returned for the game; but the players were nonetheless stunned. However, after the Steagles' in 1943 and Card-Pitt in 1944, Pittsburgh reverted to using the single-wing formation through 1952, becoming the last NFL team to ever use it as its primary offensive set.
