Which heavyweight champion had the best record in history and why?

[Keleneki]

Who had the best record out there in the heavyweight division of all time?
Muhammad ali
Lennox lewis
rocky marciano
larry holmes

any others everyone?

Great list. I would also add George Foreman. It is so amzing to me that both he and Larry Holmes had such great success in the second careers. Too bad that the window for when they could have fought one another was so small and we missed that great encounter.

Come to think of it, I would also add Joe Louis to the list. What a thing his rematch was with Max Schmeling. Who can imagine the pressure that he was under with those conditions (the only fighter to ever beat him professionally at that point in time, the whole world stage, ...). The importance of that one fight alone makes Louis worthy of said list, let alone everything else that he accomplished.

Of course Marciano...
I enjoyed Holmes Reign. Even though the opposition wasn't all that great, I enjoyed watching his style. he did go 47? 48? - 0 until Spinks came along.

Marciano. Undefeated. This thread is now worthless.
