It's one thing for Louis to have 21 defenses by age 27. But people don't understand how many of his opponents were on historic trajectorys if not for Louis, WWII or something being in their way.

In my opinion, Joe Louis is the greatest heavyweight of all time by a mile. No one comes close to him - not Ali, Lewis, Usyk, or the Klitschko brothers. All of them are far behind him when it comes to career achievements, dominance, and pure boxing skill.
