I am not trying to say he isn't great, but IMO its just hard to stand by and let people put him in the top 5 best heavyweights when there are guys like Johnson, Louis, Tunney, Demspey, Langford, Ketchel who had already fought before him and then guys like Ali, Holmes, Frazier, Foreman, Holyfield... I just can't see him being placed higher than them or even Lennox Lewis who some might find suprising but I think he does well against almost anyone who ever fought at heavyweight.
