Miller was a champion runner who was rated the fastest runner in the league's inaugural season. He headed the League's try-scoring list in that first season – he scored a hat trick of tries in that year's semi-final and followed that up with a further two in the final. Miller shares a record with Hamiso Tabuai-Fidow for the longest streak of tries scored at the beginning of their team's inaugural season, having scored at least one try in each of Eastern Suburbs' first six games. He was also the League's top point scorer in season 1908. His only representative match came in that first year when he was selected to represent Sydney in a match against a touring New Zealand Maori side.
