Floyd is a man in constant need of attention and admiration. This is a man who went to a club and threw fake cash around to create a scene for himself. Even if he wasn't like this before, it would then be life imitating art, someone who got so caught up in creating a persona that he becomes him. Even if Floyd has other parts to him, this is part of his real personality.
I think Floyd is a nice dude, and during his early years in the game he was known as a nice kid who was genuine, I did see a shift in his personality in the early 2000's when some of the media claimed he was ducking Paul Spadafora which is not true, so I think in his own way he adapted to how the media treated him more or less.
It really does not matter, the man pays none of our bills. All i care about is the skills in the ring. How you act outside of it does not effect me in any shape or form. This is not a personality contest, its not a beauty pageant. Its boxing.
