Because you can't be badass and whiny at the same time. i.e. Cormier and Rockhold
Luke Rockhold and Cormier are unusually whiny? I don't see them as acting entitled or making excuses more so than some of the other guys who have been featured, for example Dan Henderson or Jon Jones. If that is enough to disqualify Rockhold, it is clearly enough to disqualify Jon Jones, the Diaz brothers and even Frankie Edgar.
