Who is O.J. Simpson?

O.J. Simpson is being held without bail in a local jail in Las Vegas.

This latest fiasco has something to do with sports memorabilia, hotel rooms, guns, gangs and so on.

But amidst all that has been written and all the hours of CNN and Larry King devoted to Simpson in recent years, there is one thing I have yet to hear:

What kind of a shnuck is this guy actually? Is he a major pain in the ass? Is he pleasant? Funny? Volatile? Vengeful? Respectful? Even-handed? Under-handed? Was he a good teammate in his football years?

We are all convinced that Simpson is innocent or guilty of murder. But what do we really know about this guy?
