I think that is why they thought it was such a good deadlift at the time considering he wasn't a powerlifter working on that lift. Bill's routine meant lots of pulling - cleans, clean pulls, good mornings etc. He got lots of lower back work anyway.
Doesnt mean Bill was anti-deadlift though. He's written plenty of articles stating the importance of doing it for all ages and sexes - he's love ya work Markos.
