However you spin it, we are comparing a man who was the best in the world, who beat a lot of contenders, to somebody who built his resume on men ranked outside the top ten. You can't get round that simple fact. With contenders the opposite happens. A contender from Dempsey's era, is less likely to get his dues than a contender from Tua's era. The equivalents of the men that Tua beat, in Dempsey's era, you wouldn't even mention in Dempsey's defense today! You seem to counter facts with speculation here. We don't know how Firpo would do in another era, but we do know that he was one of the best contenders of his own era. Exactly the kind of scalp that is conspicuously missing from Tua's resume!
