Not a good sign. He appears to have gone sideways (mentally) 2 days in a row.
I seriously doubt it's roids, as these guys get tested before and after every fight.
His toughest opponent has always been the demons in his head. I've met him a couple times, and he's a very funny, very likable guy. I hope this doesn't turn out bad (worse).
The UFC can't risk a liability such as that. Granted, it's their own doctors testing, yet I still don't believe that the UFC would allow 'roids after already having fined their top tier fighters and stripping their belts.
IMHO, I believe it's a serious case of Depression.
I believe the second incident was faked to make him appear mental and avoid incarceration from the felony's committed in the first incident. I used that same gambit after I murdered my neighbor for pissing in my flower beds. I did some hard community service for sure but it beats the hangman.
