Smyth was strong runner. He was able to run over opposing linemen due to his size. However, he was also an effective passer. Although he completed 25% of his passes, his passing average was better than 20-yards per completion. He also led the league in both touchdowns rushing and touchdown passes thrown, matching the record held by Jimmy Conzelman from the 1922 season. On defense, he may also have tied for the NFL lead in interceptions however no official statistics were kept at the time.
