As usual with Disney sports shorts, most names are taken from the animators, including Jack Kinney, Al Bertino, Norman Ferguson, Art Riley, Bill Berg, Don DaGradi, Jack Hannah, Carl W. Stalling, Charles Nichols, Milt Kahl, and probably more.
To add to the chaos of the final melee, director Jack Kinney added incongruous scenes from other Disney films, including Victory Through Air Power (1943), Pinocchio (1940), and Kinney's own How to Play Baseball (1942) and How to Play Football (1944).
The team name of the Loose Leafs is spelled with the grammatically incorrect plural of "leaf"... but then, so is the real-life Toronto Maple Leafs; it's likely the Loose Leafs are a parody of them.
