Strydom never had a great back, but the issues in the 88 comparison pic are probably worse than normal. IIRC, that was the year he did a massive weight loss three weeks prior to the Olympia, becasue he lost the Chicago Pro to Jon Hnatyshack (sp?) due to condition.
He then over dieted, etc and lost a lot of bulk.
I still don't think WBF Stydom wins, but it would be a bit closer.
