He has no legacy. He's only liked for being the guy who's in the ring when a surprise challenger for his title came out every week, and being a radio show meme. Other than that he was the worst and set WWE back twenty years. A Hulk Hogan for the brain dead and children. He also did exactly what The Rock did at a less impressive level, he's a hypocrite. The best thing he did in his career is not marry Nikki Bella.
