A lot has been made out of Brock Lesnar's anything but gracious post fight speech.
After Lesnar destroyed then title holder Frank Mir he proceeded to insult Mir and the beer he drank, while going on to proclaim he might sleep with his wife that night.
If NFL commissioner Roger Goodell heard this come out of the mouth of one of his employees (NFL players) there would be a fine and a possible suspension.
Luckily for the rest of us, the UFC doesn't operate like that. President and owner of the UFC Dana White lets his fighters speak freely and makes sure that the best fighters fight the best opponents (listen up boxing).
In a sports community bent on being a professional business, the UFC has found it's niche in being the very thing this country was built on: freedom of speech and the pursuit of greatness.
