That is an on form Ali for 1978, a few slurs but still sharp!

Jack Johnson was a man that did not know fear. the White man threatened him and hated his guts, and they wanted to kill him, and he would stand right in front of the white mans face and say. I am still here, the Heavyweight champion, and you guys have threatened me and spit on me for years swearing your revenge and saying that I would die, I am still here. He was afraid of no one. You could stick a gun in Jack Johnson's face and he would not even flinch.
