I don't think the modern fighters have an edge with modern training techniques: I believe that that is a hindrance. I believe that old time fighters had an edge in quality of opposition and in "field" education. Now, Moore failed to win the HW title because he couldn't beat Marciano. Neither could Moorer. Foster lost to Ali and Frazier and so would Moorer. Moorer beat Holyfield, and Foster would have, probably, Moore would have certainly, and Tunney would have massacred Evander.
