Although this photo of the football team at the Tempe Normal School (now Arizona State University) is obviously posed, especially showing the year on the football, the guys are wearing their full uniforms as they would wear during a game. The main difference during a game, of course, is that they would be covered with mud.
The N on their jerseys stood for "Normal", and although it sounds kind of goofy now, was what a school that taught teaching "norms" was called back then. Yes, it was a teacher's college.
Then, as now, football was wildly popular. And as the school grew, the team went from being called the Normals, to the Bulldogs, to the Sun Devils of today.
