Using the N word, or being accused of some sort of domestic assault are the two unforgivable sins right now. Do not even have to be proven. The accusation is all that is necessary.
And if you do what Brock Edwards did in Austin a decade ago ... i.e. beat the hell out of another guy, then that requires a one game suspension. But hit a woman, or just be accused of it, even if she hit you first, then you are, according to some media types, confined to a convent until you are too old to play any more.
