As I said before, either of the Klitschkos would have been a champion from 1900-1960, without any real difficulty. Chris Byrd probably would have been a champion too, and it is not unreasonable to assume that Chad Dawson, Adamek could have won titles along the way. Personally, the notion of a 210lb Adamek having much difficulty with Jack Johnson or Jess Willard is quite preposterous.
Joe never would have gotten close. Sorry, but Wlad obliterates the man. It's Ray Mercer all over again, just a lot lot sooner.
WHAT?? Joe Louis had slow feet, he was 6', 200lbs......if he can get in range, reach up and bomb away, yeah, sure, maybe. But I mean Billy Conn gave him hell with his jab...what's Wlad gonna do?
