In Rome's defense on this, I don't think that he thought Everett would really do it. Everett said, "If you call me that one more time..." and Rome interrupted and said, "Chris" and then Everett came over and took a swing. At least give Rome credit for not backing down and calling him Jim.
And honestly that was back when Jim Rome was relatively unknown. He might have just been trying to do something drastic to get his name out there. And if that was his intentions, it worked.
