I think that mayweather might be depressed, he can't stand critics anymore although he dissimulates it. They don't like him and don't appreciate his style! They deserve to not watch any pacman-mayweather as a punishment. They all his career have kept him underrated. Etc. They don't know anything about the power of peds and about styles etc.
And he thinks he will lose to pacman because he is too old now. I guess, just guess
