I haven’t heard that, certainly possible, the video mentions he suffered from a lot of injuries.
My knowledge of Matt comes from Old M& F magazines, back in the 80’s around 84-5 from memory. I no longer have those magazines. I’m really kicking myself getting rid of them but I have no space to keep em.
Matt was big for his time, really big. It was him, Lee Haney and Victor Richards. They all seemed a bit too big at the time,compared to their contemporaries, but their physiques have aged really well. By today.s standards they are all very aesthetic.
Matt had those massive calves, actually they were fully grown bulls.
Thanks to Chris Colucci for fixing the video(I am a massive boomer when it comes to tech).
