 There's been one player to wear the number 99 in the NBA. Who is he? The only 99, I would say George Mikan. No! George Mikan wore 99. It was 77, I believe. Was he 77? I'm 99% sure. 99. Okay, you're right. He might be right. I don't know. I don't know why he said George Mikan. 99. 99? There's a 99? 99.
