Miller was hired at "The Indianapolis Star" in 1968. His first duties included answering telephones in the sports department. A year later, he was moved into the sports department as a writer. One of his early assignments was a traveling reporter following the Indiana Pacers. During his career, he became a polarizing figure. In 1981, he gained attention when he accused A. J. Foyt of cheating, for which Foyt punched Miller, and the paper issued a retraction. Miller also stirred up controversy, taking on Bobby Knight, the Irsay family, girls' basketball, and female golfers. One of his heated columns led to the girls' basketball team from Franklin College challenge the paper's sports department to a match, and the sportswriters won the game.
