One thing that a lot of folks don't realize is in addition to being talented Joe Greene was also a bit bigger than his competition. He had talent and size plus desire. Joe Greene was a great ball player who was likely held as much as Harrison was in his era. I remember watching one game at my grandfathers house and my grandfather was bitching a blue streak about all the holding and how it wasn't being called. The Steelers linemen had a great many torn and ripped jerseys in that game. That was back when Pittsburgh had a Post and a Gazette for any that are curious, there was also a bread called Town Talk and Bob Prince was the voice of the Pirates.
