Hopkins versatility and adaptability are sublime. He had zero workrate issues at his 160 peak and hit quite hard. He had no weaknesses and sure as hell could find yours. He could easily take away an opponents jab. He could also mix things up and spoil so much that even a superlative counter puncher like McCallum would not settle into a winning rhythm.
He is not gonna beat Mc Callum with power or workrate.As for ring intelligence, Mc Callum was in nothing behind Bernard.They are both pretty even in my view but the key here seems to be the jab of Mc Callum
The fans would definitey be the losers after this one. Unless your looking for a cure for insomnia. Both guys getting by on Ring IQ and exp.
Old McCallum at light heavy still better than the likes of Pascal , Cloud and Shumenov. Harding was probably then Pascal too because of his fitness and worrtrate. Pascal suited Hopkins because he had poor stamina and could only box in sporadic spurts.
