I mean, he was pretty badass. Still is to an extent, just not the same kind of irreverent badass fighting dudes in hospitals and conducting incoherent interviews that lasted forever, while casually dropping lines that would be repeated forever in MMA fandom. Now, he's creeping up on 40, and like it or not, time wears down every man. Changes him. I don't feel sorry, per se, because I don't know if Diaz ever really cared about living up to those expectations.
