His journey began in Milwaukee, Wisconsin, where his raw talent and imposing stature caught the eye of Knute Rockne, the legendary Notre Dame coach. Rockne, known for his keen eye for talent, recognized Miller's potential and recruited him to South Bend in 1926.

Miller didn't disappoint. He quickly established himself as a cornerstone of the Irish defense, earning All-American honors in 1928 and 1929. His strength, agility, and intelligence made him a formidable wall against opposing offensive lines. He anchored the "Four Horsemen" era, a period of offensive dominance for Notre Dame, providing the defensive stability that allowed stars like Stuhldreher and Laycock to shine.

Beyond his physical prowess, Miller was known for his leadership and unwavering dedication. He served as team captain in 1929, leading by example both on and off the field. His loyalty to Notre Dame extended beyond his playing career, as he returned to serve as an assistant coach after his graduation in 1929.
