Yes, I do think he bulked up, particularly in the thighs and trunk. (I do not believe his left arm could've been any bigger.)
Take a look at him in 1976; a good shot of him from the back is at 0:20 or 0:41: http://www.youtube.com/watch?v=7-VeBIal8TU
You may be right. Didn't Hopman get the Aussie team to work with weights when they trained?
