I never understood the Vince logic of being babyface.  When Austin turned face, he didn’t change anything.  And he stayed over.  When Rock turned face (after backlash), he didn’t change anything.  Yet when Roman turns face, he changes.  When Cena turned face, he changed. When Diesel turned face, he changed. 

Because Austin and Rock were characters that got over on their own, I think, whereas the others were Vince wanting to recreate Hulk Hogan.
