First of all, I was in attendance at the Chicago Bulls- New York Knicks game (in case you are wondering, I was two sections over from the "incident.") It is unfortunate that "the incident " marred what was probably the most exciting non-playoff NBA game that I have witnessed in person. Bottom line, for whatever reason he may have had, Antonio Davis crossed the line, literally and figuratively. He MUST be suspended by the NBA. In my opinion for a minimum of two games. Make sure you read the version of the facts from the fan who was allegedly threatening Davis' wife:
