Have boxers gotten better as time progressed?

Yeah probably the same as most other modern heavyweights.

 

-Don't forget Tyson broke Ruddock's jaw knocked R. down two times
on the rematch! And Ruddock headed to the hospital after the fight.
And it was the 100% prime Ruddock.
-It's true, Tyson didn't knock Tillis out but i think he didn't want to knock
him out.Can you imagine a green,young fighter without longer fight experience?
-ko ratio means nothing without the analysis of the other circumstances.
1.
For example a cut ko is nothing to do with power
2.Ko by mental problem is nothing to do with the punching power.
3.The ko percentage by fight number sucks because this thing ignores
the round numbers.
1 round fight = 1000 rounds fight by this stupid fight/ko number
statistical stupidity.
Forget the traditional ko ratio and use the round/ko number ratio this is
bad thing also but far better than the total lame fight/ko number crap !:tired

 

I usually do try to look into KO ratio's a bit deeper than most. For example with old timers I usually check if the KO victoms of a certain fighter had winning records ( like most of later Sandy Sadlers) or good chins. I could go even further but I'm not one to over analyse too much. I cant be arsed.
