Does the fact that Jack Johnson era fighters were drying out exclude them from h2h?

Also, shouldn't this apply to every fighter that cuts a **** load of weight in the modern era?

I.e you cannot match up todays flyweights with the flyweights of the past?

 

or ANY weight division either Flea, even HWs are a bigger beast and completely a different weight division.

 

Yeah, but they're not cutting weight.

And todays cruiserweights would be solid 210lb heavyweights in any other era.

There are exceptions to the rule; Floyd and Manny are 'natural' welterweights, although Pacquiao would've likely never been at flyweight and would've made featherweight briefly, and really been a career lightweight and welterweight.

Hopkins and Kovalev don't come in much over the light heavyweight limit.

Rigondeaux could make 122lbs in any era, or would be a decent sized featherweight (not today, as most of today's featherweights are really light welterweights)

There are a few exceptions of course. And there are fighters from other eras who squeezed into their weight class and would be much more comfortable today (Lamotta, Dick Tiger)

 

yes there are always some exceptions but I agree whole heartedly and have stated the same for years.

and of course the same the other way round too, i.e. yesterdays Middleweights are todays Welterweights and/or junior weights, in & around it, and throughout all the weights!

 

Yep....but for the majority of todays fighters there are substituting the sharpening of their tools in their training time for cutting weight instead, and it shows in the level of operator we see today.
