I guess he's realising the opportunity given to him to fight in the UFC and is taking it seriously. You can't be a fucktard and train at an elite Gym like Xtreme Couture, the others won't tolerate it.
It'd be easy to write off Browning as a lost cause, but its not like fighters are all upstanding citizens. Dumbasses can succeed in any sport if they work hard enough. Hopefully watching the show has been enlightening to Browning and he has turned it all around, but only time will tell.
