I think the Jackson fight would be close ,but give the edge to Jack.Johnson was an improved version of Corbett I think and considerably bigger,so I take him to outpoint Corbett.Fitz was rather too easy to hit for him to outpoint Johnson ,though his power would allways be a factor ,I think Johnson's defence would see him take a dec in a rather lack lustre affair.So Johnson wins them all ,but then I rate Johnson considerably higher than most on here.
