Who ,of the men ,who have been linear champion, has been the most durable ,and impervious to punishment? My vote is Jim Jeffries. Any one want to argue the point?
Altho his reign as champ suggests otherwise, I imagine early prime liston to be very durable. Obviously rocky marciano is right up there also. Bowe was quite durable and perhaps more so had he taken training more seriously.
Of course.the great Muhammad must be one of those on top of the list. Holmes and Marciano also figure.
Ali, Holyfield, Frazier, McCall, Holmes, Foreman ..... Sorry Rocky guys, you have to fight big punchers to qualify ... I'd throw in Vitali too ... a hell of a chin ...
