Nobody cared about looking like the common man.
Tank represented the common man but everyone knew he was anything but common. A man built like a bull with a civil war general face, can bench 600 lbs with hammers for hands and a thirst for violence and alcohol. He's the "I know a guy down at my bar who can tear that tiny bantamweight's head off" guy and that's why people loved him. The closest guys we have to that is Derrrick Lewis and Tai Tuivasa.
Chris Daukus? He used to be a fatty that people picked on in high school, now he's a fatty who lost a ton of weight but still has fat folds flapping around.
Tank's built like a powerlifter, Daukus's built like a DDP yoga feel good story. Unless he can get himself a more aesthetically pleasing physique, he's not attracting any crowds anytime soon.
