I dont think so , HE was directed to train flexable hip movements and knee bends and heel lifts all into the walk that we always saw him do.
He would bend at the waist,Fists up next to his ears ,elbows down,he would come in low and bending from left to right so that his opponent couldnt get a clean shot off. All the time he was peek a booing in between looking for the space to throw a shot up. When he threw it had the other hip comming around as well as his leg straightening and his heel lifting so he was an evasive KO artist all in one set!
I wouldnt say he could dance the night away like some though,he just wasnt built that way.
His trainers were smart they worked with what he bought to the table naturally as far as his build went.

People with not so good head movment (like thick necked ,high shouldered heavyweights can still get it from stretching and training other parts ,so that the movment and bending and flex from their ankles up to their hips transfers up to the head.
