He punched Bulls teammate Steve Kerr in the face during a scrimmage.
Kerr said he talked back to MJ during training camp, and then:
He punched me in the face … It was one of the best things that ever happened for me. I needed to stand up and go back at him. I think I earned some respect. But, we have a great relationship ever since … you gotta prove it, and then once you prove it, you’re fine.”
