49 and 0 wont be his last fight. Duplicating Marcianos record wont be enough. He will go for 50. And he could fight Taylor Swift and get 50 million. Then he retires. I bet he waits a year or so and then mimics Leonard by coming back. He will then make 100 million and even if he loses its does not matter. He tied and then beat Marcianos retirement record.
