PART 2 - Thomas Hearns is an American former professional boxer who competed
from 1977 to 2006. Nicknamed the "Motor City Cobra", and more famously
"The Hitman", Hearns' tall, slender build and oversized arms and
shoulders allowed him to move up over fifty pounds in his career and
become the first boxer in history to win world titles in five weight
divisions: welterweight, light middleweight, middleweight, super
middleweight and light heavyweight.
