Who do you think has caused the most damage to their legacy for their post-wrestling ring antics? CM Punk has to be one of them. He’s gone from fans practically bawling at him quitting wrestling to simply rolling their eyes everytime he talks (Daniel Bryan seems to have replaced him as the ones fans miss the most.) Whenever Bret Hart talks, people respond with a "Oh look, Bret’s whining about something again." Before he made peace with the WWE (and then died) Warrior was definitely in this category. I know he’s still wrestling, but would Kurt Angle fit in here?
I feel like Chris Benoit did some long-term damage to his brand, in a sense.
