There has been endless Marciano threads about his opposition but I cant seem to remember any threads discussing his sparring partners in detail, who he used, did he spar with any large, young talented, fast guys who were on the way up to test him and get him in shape ? If so how did the sparring go .. ? I'm rereading the decent Ezzard Charles bio and it made me think about this a bit .. any Marciano scholars out there with some details ?
