Both of their fights were great fights. Marciano had a concussive power that hurt opponents a lot more than you could tell from watching, unless the camera was at a close-up. Some of the still shots of fight one show Ezzard face horribly distourted. He landed a some great shots too.
I have seen Bivins on film before. He's a tad boring. The skills are there but he did not hit hard enough to get the respect of his opponents. Jones to me had faster hands, and hit harder. Toney to me was far more durable, and better on defense and the counter.
80 1/2 reach for Bivins? Box rec says 76". Do you have other sources of newspapers where the article says Bivins was measured and his reach was 80 1/2 inches? http://www.boxrec.com/list_bouts.php?human_id=9974&cat=boxer
