Thomas Hearns vs. Julian Jackson at 154.

[Ron Swanson]

Agreed, you have to pick Tommy but every moment would be terrifying if you had money on it.

Hearns chin is underrated by the way. 67 fights, stopped 4 times. One was as much by exhaustion as his chin failing. One was by injury when he was very old. His chin cost him 2 of 67 fights and it was thunderous blows each time.
