Marciano and Generational Bias

[holmcall]

Aside from some evolutionaty factors, the heavweight division is the only one that has been variable--as fighters get bigger and bigger. The other weight classes have remained fixed.

That is true, but the additioin of additional divisions such as SuperMiddle, Cruiser etc. has removed fighters that in the past would have been relatively small/large at a particular weight.
