Well when ranking the top ten greatest you got look at a few things really. That being resume, defenses, and how long they reign over as champ. With Wald resume is the kicker really but i don't think its as bad as most think it is. Bryde, Chagve, Haye, Peter, Povetkin and Maybe Brewster besides the 70's and 90's i think those guys would be fine with most of the contenders of all the other eras not saying the champs. Not sure were to rank the man but if he keeps being champ and winning ever fight with out losing hardly any rounds its going to get hard not to.
