So, just to be clear - he was talking about practice, there?
Actually, I didn't learn this until just recently, but Iverson apparently had some heavy stuff going on that day, which boiled over into that press conference. His best friend had just been killed; in addition, he thought the press conference was going to be about Iverson not being traded from the 76ers. Someone asked what appeared to Iverson to be a question from way out in left field, about practice. That kind of triggered the "practice" rant.
