How long should a Great Boxing career last? (# of title defenses)

[Max Power]

Well longer it lasts the greater if everything else is equal.

But in practice there are other factors like Quality of opposition.

The number of quality opponents beaten at championship level is the best measure because some fighters like to pad up their record with bums.

Also it's weight class specific. The lighter the weight, the more fights you can have against quality opposition.

Obviously at HW one fight is worth far more than a fight at any other weight.

Good point.

The smaller weight class usually have more fights or options. So would that mean they can burn out quicker?

A feather @ age 30 is equivalent to a HW @ age 35? (if their level of comp assumed is the same?)

Specific- the thread Berto-Lopez was stated Berto may not be able to fight top opposition. But I questioned- maybe he has?? 10 years in the game, 3 -4 years to get title shot.
When he did -won & held it for a about 4 years.

NO right or wrong answer - I just question: Isnt that sufficient to call him at least a durable champion?

Flip the script_ if a fghter holds any belt(s) longer than 5 years, doesnt that open up the argument that it HAD to have been padded? Or that the class was weak as hell?
Kind of a double edged sword question I guess! If a fighter loses a title after 4 years then he aint shit. But if he holds it longer than 5, well he fought soft opposition.

Just wondering if you or anyone here can present a case where someone did more in 10 years than someone in 20 years? Once again no right or wrong; all opinions welcome!
