What is the reason why floyd do not answer with the negative comments against him?

Floyd has been called as coward and chicken. Floyd do not answer anything. If they charged you something and you can not even talk a single word to defend yourself, the phsychologist will say "You are Guilty as Charged". I can not believe, Floyd just turned his back to his boxing fans to tell He will be off by a year or 2. To regain his honor, he must answer this week and must proclaimed by hinself to fight PACMAN next mid-year, without middleman/negotiator. If he don't do this, floyd is considered as coward and chicken as claimed by majority.
