One thing that is absolutely amazing about Valuev is his physical conditioning...His punch output is excellent, no stamina issues...and he never seems to come down with the physical injuries athletes his size always seem to have...I just don't get this guy

As far as his skills well nothing great, he seems to fight "small" fighting down to his opponents height which will one day get him in trouble...but otherwise decent. I'd really like to see him fight either Klitschko which would be revealing for both sides..
