Very unorthodox..right down to those gimpy knee wraps of his. Most unorthodox is Oscar Bonavena...he just schlepped along without a plan sometimes..he sure puzzled Joe Frazier
Another guy not mentioned yet is Snipes. I always liked the guy, and put him in that category of a junk fighter. Funny how those junk fighters--another would be Mayorga--always see to bother some better fighters with their oddball style. But they'd better have a set of whiskers with that style.
What about Ken Norton? I always thought the way he moved; dragging his leg behind him and the way he let his hands go; that swinging right hand over the top, was sort of unique.
