What unorthodox about PBF's defense? He uses his shoulder and he rolls with punches... He has the most coventional defense besides Winky's. Same with Archie Moore, Toney, etc. I think Winky in ways has an orthodox defense ,and same with Duran because they come foreward on the defensive which is unique for the large part. RJJ only orthodox defense was putting his back to the ropes, but either than that he didn't really have defense because he was a pure counter puncher.
